The Hawkins Electrical Guide was a technical engineering book written by Nehemiah Hawkins.
First published in 1914, intended to explain the highly complex principles of the new technology of electricity in a way that could be understood by the common man. The book is notable for the extremely high number of detailed illustrations it contains, and the small softbound size of the volumes.The book was published by Theodore Audel & Company, and the majority of the illustrative content became the basis of decades of follow-up books published under the Audels brand name. Because the Hawkins Electrical Guide was printed in the United States prior to 1923, the content of the books has passed into the public domain.
Free media access on the Internet. Chapter 14: The Dynamo: Current Commutation. Chapter 15: Classes of Dynamo.Chapter 19: Theory of the Armature. Chapter 20: Commutation and the Commutator. Chapter 35: Operation of Motors. Chapter 68: Wave Form Measurement. Due to several book digitizing initiatives such as the Gutenberg project. And The Hawkins Electrical Guide Online. (archived March 21, 2015), many of these older public domain books are becoming available on the Internet. This series of books is currently available for free, non-commercial use from Google Books.

Some electrical engineers design complex power systems on a macroscopic level. Electrical engineers also design microscopic electronic devices and electronic circuitry, which achieved the record setting length of 1 nanometer. For a single logic gate. Electrical engineering is a technical discipline concerned with the study, design and application of equipment, devices and systems which use electricity.It emerged as an identified activity in the latter half of the 19th century after commercialization. Electrical engineering is now divided into a wide range of fields including, computer engineering. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics, and electrical materials science.
See glossary of electrical and electronics engineering. Electrical engineers typically hold a degree. In electrical engineering or electronic engineering.Practising engineers may have professional certification. And be members of a professional body. Or an international standards organization. These include the International Electrotechnical Commission. (IEC), the Institute of Electrical and Electronics Engineers.
(IEEE) and the Institution of Engineering and Technology. The IEC prepares international standards for electrical engineering, developed through consensus, thanks to the work of 20,000 electrotechnical experts, coming from 172 countries worldwide. Electrical engineers work in a very wide range of industries and the skills required are likewise variable. These range from circuit theory.To the management skills of a project manager. The tools and equipment that an individual engineer may need are similarly variable, ranging from a simple voltmeter.
To a top end analyzer to sophisticated design and manufacturing software. Main article: History of electrical engineering. Has been a subject of scientific interest since at least the early 17th century. Was a prominent early electrical scientist, and was the first to draw a clear distinction between magnetism. He is credited with establishing the term "electricity".
He also designed the versorium. A device that detects the presence of statically charged objects. In 1762 Swedish professor Johan Carl Wilcke.Invented a device later named electrophorus. That produced a static electric charge. Had developed the voltaic pile. A forerunner of the electric battery. The discoveries of Michael Faraday. Formed the foundation of electric motor technology. In the 19th century, research into the subject started to intensify. Notable developments in this century include the work of Hans Christian Ørsted. Who discovered in 1820 that an electric current produces a magnetic field that will deflect a compass needle, of William Sturgeon. Who, in 1825 invented the electromagnet. Who invented the electrical relay.
In 1835, of Georg Ohm. Who in 1827 quantified the relationship between the electric current. The discoverer of electromagnetic induction. In 1831, and of James Clerk Maxwell.
Who in 1873 published a unified theory. In his treatise Electricity and Magnetism. In 1782 Georges-Louis Le Sage.Developed and presented in Berlin. Probably the world's first form of electric telegraphy, using 24 different wires, one for each letter of the alphabet. This telegraph connected two rooms. It was an electrostatic telegraph that moved gold leafs through electrical conduction. In 1795, Francisco Salva Campillo.
Proposed an electrostatic telegraph system. Salvas electrolyte telegraph system was very innovative though it was greatly influenced by and based upon two new discoveries made in Europe in 1800 Alessandro Voltas electric battery for generating an electric current and William Nicholson and Anthony Carlyles electrolysis of water. May be considered the first example of electrical engineering. Electrical engineering became a profession in the later 19th century. Practitioners had created a global electric telegraph.
Network and the first professional electrical engineering institutions were founded in the UK and USA to support the new discipline. Created an electric telegraph system in 1816 and documented his vision of how the world could be transformed by electricity. Over 50 years later, he joined the new Society of Telegraph Engineers soon to be renamed the Institution of Electrical Engineers.
Where he was regarded by other members as the first of their cohort. By the end of the 19th century, the world had been forever changed by the rapid communication made possible by the engineering development of land-lines, submarine cables.
And, from about 1890, wireless telegraphy. Practical applications and advances in such fields created an increasing need for standardised units of measure. They led to the international standardization of the units volt. This was achieved at an international conference in Chicago in 1893. The publication of these standards formed the basis of future advances in standardisation in various industries, and in many countries, the definitions were immediately recognized in relevant legislation.
During these years, the study of electricity was largely considered to be a subfield of physics. Since the early electrical technology was considered electromechanical. Founded the world's first department of electrical engineering in 1882. The first electrical engineering degree program was started at Massachusetts Institute of Technology. (MIT) in the physics department under Professor Charles Cross.Though it was Cornell University. To produce the world's first electrical engineering graduates in 1885. The first course in electrical engineering was taught in 1883 in Cornells Sibley College of Mechanical Engineering and Mechanic Arts.
It was not until about 1885 that Cornell. Established the first Department of Electrical Engineering in the United States. In the same year, University College London.
Founded the first chair of electrical engineering in Great Britain. Weinbach at University of Missouri. Soon followed suit by establishing the electrical engineering department in 1886.Gradually started to offer electrical engineering programs to their students all over the world. Electric light and (DC) power supply networks. Practical polyphase (AC) and induction motor designs. Developed standard 3-phase (AC) systems. AC mathematical theories for engineers. Developed theoretical models for electric circuits.
During these decades use of electrical engineering increased dramatically. Switched on the world's first large-scale electric power network that provided 110 volts direct current. (DC) to 59 customers on Manhattan Island. In 1884, Sir Charles Parsons.Allowing for more efficient electric power generation. With its ability to transmit power more efficiently over long distances via the use of transformers. Developed rapidly in the 1880s and 1890s with transformer designs by Károly Zipernowsky. (later called ZBD transformers), Lucien Gaulard.
Were independently invented by Galileo Ferraris. And further developed into a practical three-phase. And Charles Eugene Lancelot Brown. Contributed to the theoretical basis of alternating current engineering.
The spread in the use of AC set off in the United States what has been called the War of Currents. Backed AC system and a Thomas Edison backed DC power system, with AC being adopted as the overall standard.
Known for his pioneering work on long distance radio transmission. During the development of radio.The mathematical work of James Clerk Maxwell. During the 1850s had shown the relationship of different forms of electromagnetic radiation.
Including possibility of invisible airborne waves (later called "radio waves"). In his classic physics experiments of 1888, Heinrich Hertz. Proved Maxwell's theory by transmitting radio waves. And detected them by using simple electrical devices. Other physicists experimented with these new waves and in the process developed devices for transmitting and detecting them.Began work on a way to adapt the known methods of transmitting and detecting these "Hertzian waves" into a purpose built commercial wireless telegraphic. Early on, he sent wireless signals over a distance of one and a half miles. In December 1901, he sent wireless waves that were not affected by the curvature of the Earth. Marconi later transmitted the wireless signals across the Atlantic between Poldhu, Cornwall, and St.
John's, Newfoundland, a distance of 2,100 miles (3,400 km). In 1897, Karl Ferdinand Braun. Introduced the cathode ray tube. As part of an oscilloscope.
A crucial enabling technology for electronic television. Invented the first radio tube, the diode. Two years later, Robert von Lieben. Independently developed the amplifier tube, called the triode.Which would eventually lead to the development of the microwave oven. In 1946 by Percy Spencer.
In 1934, the British military began to make strides toward radar. (which also uses the magnetron) under the direction of Dr Wimperis, culminating in the operation of the first radar station at Bawdsey. The world's first fully functional and programmable computer using electromechanical parts. Designed and built the Colossus.
The world's first fully functional, electronic, digital and programmable computer. (Electronic Numerical Integrator and Computer) of John Presper Eckert. Followed, beginning the computing era. The arithmetic performance of these machines allowed engineers to develop completely new technologies and achieve new objectives, including the Apollo program. Which culminated in landing astronauts on the Moon.
A replica of the first working transistor. The invention of the transistor. In late 1947 by William Shockley. Of the Bell Telephone Laboratories. Opened the door for more compact devices and led to the development of the integrated circuit.
In 1958 by Jack Kilby. And independently in 1959 by Robert Noyce. Was introduced with the Intel 4004. It began with the Busicom. Conceived of a single-chip CPU design, which he discussed with Busicom and Intel.
The Intel 4004 was then developed as a single-chip microprocessor from 1969 to 1970, led by Intel's Marcian Hoff. And Busicom's Masatoshi Shima.
The microprocessor led to the development of microcomputers. Electrical engineering has many subdisciplines, the most common of which are listed below.
Although there are electrical engineers who focus exclusively on one of these subdisciplines, many deal with a combination of them. Sometimes certain fields, such as electronic engineering and computer engineering. Are considered separate disciplines in their own right. Power engineering deals with the generation.
As well as the design of a range of related devices. High voltage engineering, and power electronics. In many regions of the world, governments maintain an electrical network called a power grid.That connects a variety of generators together with users of their energy. Power engineers may work on the design and maintenance of the power grid as well as the power systems that connect to it. Such systems are called on-grid power systems and may supply the grid with additional power, draw power from the grid, or do both.
Power engineers may also work on systems that do not connect to the grid, called off-grid power systems, which in some cases are preferable to on-grid systems. The future includes Satellite controlled power systems, with feedback in real time to prevent power surges and prevent blackouts.
Play a critical role in spaceflight. Of a diverse range of dynamic systems. And the design of controllers. That will cause these systems to behave in the desired manner.
To implement such controllers, electrical engineers may use electronic circuits. Has a wide range of applications from the flight and propulsion systems of commercial airliners. Present in many modern automobiles.
It also plays an important role in industrial automation. Control engineers often utilize feedback. For example, in an automobile.
Is continuously monitored and fed back to the system which adjusts the motor's. Where there is regular feedback, control theory.
Can be used to determine how the system responds to such feedback. Electronic engineering involves the design and testing of electronic circuits. That use the properties of components. To achieve a particular functionality.
Which allows the user of a radio. Out all but a single station, is just one example of such a circuit. Another example to research is a pneumatic signal conditioner.
Prior to the Second World War, the subject was commonly known as radio engineering and basically was restricted to aspects of communications and radar. Later, in post war years, as consumer devices began to be developed, the field grew to include modern television, audio systems, computers. In the mid-to-late 1950s, the term radio engineering gradually gave way to the name electronic engineering. Before the invention of the integrated circuit. Electronic circuits were constructed from discrete components that could be manipulated by humans.
These discrete circuits consumed much space and power. And were limited in speed, although they are still common in some applications. Packed a large numberoften millionsof tiny electrical components, mainly transistors. Into a small chip around the size of a coin.
This allowed for the powerful computers. And other electronic devices we see today. Engineering deals with the design and microfabrication.
Of very small electronic circuit components for use in an integrated circuit. Or sometimes for use on their own as a general electronic component. The most common microelectronic components are semiconductor. Although all main electronic components resistors.Can be created at a microscopic level. Is the further scaling of devices down to nanometer.
Modern devices are already in the nanometer regime, with below 100 nm processing having been standard since around 2002. Microelectronic components are created by chemically fabricating wafers of semiconductors such as silicon at higher frequencies, compound semiconductors. Like gallium arsenide and indium phosphide to obtain the desired transport of electronic charge and control of current. The field of microelectronics involves a significant amount of chemistry and material science and requires the electronic engineer working in the field to have a very good working knowledge of the effects of quantum mechanics.Requires signal processing to get a red, green, and blue value at each pixel. Deals with the analysis and manipulation of signals.
Signals can be either analog. In which case the signal varies continuously according to the information, or digital. In which case the signal varies according to a series of discrete values representing the information.
For analog signals, signal processing may involve the amplification. Of audio signals for audio equipment or the modulation.
For digital signals, signal processing may involve the compression. Signal Processing is a very mathematically oriented and intensive area forming the core of digital signal processing. And it is rapidly expanding with new applications in every field of electrical engineering such as communications, control, radar, audio engineering. Power electronics, and biomedical engineering.
As many already existing analog systems are replaced with their digital counterparts. Is still important in the design of many control systems. DSP processor ICs are found in many types of modern electronic devices, such as digital television sets. Audio equipment, mobile phones, multimedia players. Camcorders and digital cameras, automobile control systems, noise cancelling.
In such products, DSP may be responsible for noise reduction. Digital media, wirelessly transmitting or receiving.
Data, triangulating position using GPS. And other kinds of image processing. Are a crucial component in the analysis of satellite information. Such as a coax cable. Transmissions across free space require information to be encoded in a carrier signal.
To shift the information to a carrier frequency suitable for transmission; this is known as modulation. Popular analog modulation techniques include amplitude modulation. The choice of modulation affects the cost and performance of a system and these two factors must be balanced carefully by the engineer. Once the transmission characteristics of a system are determined, telecommunication engineers design the transmitters. These two are sometimes combined to form a two-way communication device known as a transceiver.A key consideration in the design of transmitters is their power consumption. As this is closely related to their signal strength. Typically, if the power of the transmitted signal is insufficient once the signal arrives at the receiver's antenna(s), the information contained in the signal will be corrupted by noise. Provide pilots with the tools to control aircraft analytically. Deals with the design of devices to measure physical quantities such as pressure. The design of such instruments requires a good understanding of physics. That often extends beyond electromagnetic theory. Measure variables such as wind speed.
To enable pilots the control of aircraft analytically. To measure the temperature difference between two points. Often instrumentation is not used by itself, but instead as the sensors. For example, a thermocouple might be used to help ensure a furnace's temperature remains constant. For this reason, instrumentation engineering is often viewed as the counterpart of control.
Are used in fields as diverse as computational biology. Computer engineering deals with the design of computers. This may involve the design of new hardware. Or the use of computers to control an industrial plant. Computer engineers may also work on a system's software.
However, the design of complex software systems is often the domain of software engineering. Which is usually considered a separate discipline.
Represent a tiny fraction of the devices a computer engineer might work on, as computer-like architectures are now found in a range of devices including video game consoles. The Bird VIP Infant ventilator. Is an engineering discipline which deals with the convergence of electrical and mechanical. Such combined systems are known as electromechanical.
Systems and have widespread adoption. Examples include automated manufacturing systems.Heating, ventilation and air-conditioning systems. And various subsystems of aircraft.
Electronic systems design is the subject within electrical engineering that deals with the multi-disciplinary design issues of complex electrical and mechanical systems. The term mechatronics is typically used to refer to macroscopic. Have predicted the emergence of very small electromechanical devices. Already, such small devices, known as Microelectromechanical systems.
(MEMS), are used in automobiles to tell airbags. To create sharper images, and in inkjet printers.To create nozzles for high definition printing. In the future it is hoped the devices will help build tiny implantable medical devices and improve optical communication. Is another related discipline, concerned with the design of medical equipment. This includes fixed equipment such as ventilators. As well as mobile equipment such as cochlear implants. An example is the most recent electric propulsion. Main article: Education and training of electrical and electronics engineers. Electrical engineers typically possess an academic degree. With a major in electrical engineering, electronics engineering. Or electrical and electronic engineering. The same fundamental principles are taught in all programs, though emphasis may vary according to title. The length of study for such a degree is usually four or five years and the completed degree may be designated as a Bachelor of Science in Electrical/Electronics Engineering Technology, Bachelor of Engineering. Or Bachelor of Applied Science. Generally includes units covering physics. And a variety of topics in electrical engineering. Initially such topics cover most, if not all, of the subdisciplines of electrical engineering.
At some schools, the students can then choose to emphasize one or more subdisciplines towards the end of their courses of study. It is used as a powerful tool in troubleshooting.At many schools, electronic engineering is included as part of an electrical award, sometimes explicitly, such as a Bachelor of Engineering (Electrical and Electronic), but in others electrical and electronic engineering are both considered to be sufficiently broad and complex that separate degrees are offered. Some electrical engineers choose to study for a postgraduate degree such as a Master of Engineering. , a Master of Engineering Management. In Engineering, an Engineering Doctorate. , or an Engineer's degree. The master's and engineer's degrees may consist of either research. Or a mixture of the two. The Doctor of Philosophy and Engineering Doctorate degrees consist of a significant research component and are often viewed as the entry point to academia. In the United Kingdom and some other European countries, Master of Engineering is often considered to be an undergraduate degree of slightly longer duration than the Bachelor of Engineering rather than postgraduate. Belgian electrical engineers inspecting the rotor of a 40,000 kilowatt turbine. Of the General Electric Company. In most countries, a bachelor's degree in engineering represents the first step towards professional certification. And the degree program itself is certified by a professional body. After completing a certified degree program the engineer must satisfy a range of requirements (including work experience requirements) before being certified. Once certified the engineer is designated the title of Professional Engineer. (in the United States, Canada and South Africa), Chartered Engineer. In India, Pakistan, the United Kingdom, Ireland and Zimbabwe.
, Chartered Professional Engineer (in Australia and New Zealand) or European Engineer. In much of the European Union. Corporate office is on the 17th floor of 3 Park Avenue. The advantages of licensure vary depending upon location. For example, in the United States and Canada "only a licensed engineer may seal engineering work for public and private clients".
This requirement is enforced by state and provincial legislation such as Quebec. In other countries, no such legislation exists.Practically all certifying bodies maintain a code of ethics. That they expect all members to abide by or risk expulsion. In this way these organizations play an important role in maintaining ethical standards for the profession. Even in jurisdictions where certification has little or no legal bearing on work, engineers are subject to contract law. In cases where an engineer's work fails he or she may be subject to the tort of negligence. And, in extreme cases, the charge of criminal negligence. An engineer's work must also comply with numerous other rules and regulations, such as building codes. And legislation pertaining to environmental law. Professional bodies of note for electrical engineers include the Institute of Electrical and Electronics Engineers. The IEEE claims to produce 30% of the world's literature in electrical engineering, has over 360,000 members worldwide and holds over 3,000 conferences annually. The IET publishes 21 journals, has a worldwide membership of over 150,000, and claims to be the largest professional engineering society in Europe. Obsolescence of technical skills is a serious concern for electrical engineers. Membership and participation in technical societies, regular reviews of periodicals in the field and a habit of continued learning are therefore essential to maintaining proficiency. An MIET(Member of the Institution of Engineering and Technology) is recognised in Europe as an Electrical and computer (technology) engineer. In Australia, Canada, and the United States electrical engineers make up around 0.25% of the labor force. From the Global Positioning System. Electrical engineers have contributed to the development of a wide range of technologies. They design, develop, test, and supervise the deployment of electrical systems and electronic devices. For example, they may work on the design of telecommunication systems.
The operation of electric power stations. The design of household appliances. Is typical of what electrical engineers work on. Fundamental to the discipline are the sciences of physics.
As these help to obtain both a qualitative. Description of how such systems will work. Work involves the use of computers. And it is commonplace to use computer-aided design. Programs when designing electrical systems.
Nevertheless, the ability to sketch ideas is still invaluable for quickly communicating with others. Although most electrical engineers will understand basic circuit theory. That is the interactions of elements such as resistors. In a circuit, the theories employed by engineers generally depend upon the work they do.
Might be relevant to an engineer working on VLSI. (the design of integrated circuits), but are largely irrelevant to engineers working with macroscopic electrical systems. May not be relevant to a person designing telecommunication systems that use off-the-shelf.
Perhaps the most important technical skills for electrical engineers are reflected in university programs, which emphasize strong numerical skills. And the ability to understand the technical language and concepts. That relate to electrical engineering.
Rod, illustrating the total internal reflection of light in a multi-mode optical fiber. A wide range of instrumentation is used by electrical engineers. For simple control circuits and alarms, a basic multimeter. Where time-varying signals need to be studied, the oscilloscope.
Is also an ubiquitous instrument. And high frequency telecommunications, spectrum analyzers. In some disciplines, safety can be a particular concern with instrumentation. For instance, medical electronics designers must take into account that much lower voltages than normal can be dangerous when electrodes are directly in contact with internal body fluids.
Power transmission engineering also has great safety concerns due to the high voltages used; although voltmeters. May in principle be similar to their low voltage equivalents, safety and calibration issues make them very different. Many disciplines of electrical engineering use tests specific to their discipline. Audio electronics engineers use audio test sets.
Consisting of a signal generator and a meter, principally to measure level but also other parameters such as harmonic distortion. Likewise, information technology have their own test sets, often specific to a particular data format, and the same is true of television broadcasting. At the Misawa Air Base Misawa Security Operations Center, Misawa, Japan. For many engineers, technical work accounts for only a fraction of the work they do. A lot of time may also be spent on tasks such as discussing proposals with clients, preparing budgets.Many senior engineers manage a team of technicians. Or other engineers and for this reason project management. Most engineering projects involve some form of documentation and strong written communication. Skills are therefore very important.
Of engineers are just as varied as the types of work they do. Electrical engineers may be found in the pristine lab environment of a fabrication plant. The offices of a consulting firm.
Or on site at a mine. During their working life, electrical engineers may find themselves supervising a wide range of individuals including scientists.Electrical engineering has an intimate relationship with the physical sciences. For instance, the physicist Lord Kelvin.
Played a major role in the engineering of the first transatlantic telegraph cable. Conversely, the engineer Oliver Heaviside.
Produced major work on the mathematics of transmission on telegraph cables. Electrical engineers are often required on major science projects. For instance, large particle accelerators. Need electrical engineers to deal with many aspects of the project: from the power distribution, to the instrumentation, to the manufacture and installation of the superconducting electromagnets.
