| Electrical engineering Electrical engineering, sometimes referred to as electrical and electronic engineering, is a field of engineering that deals with the study and application of electricity, electronics and electromagnetism. The field first became an identifiable occupation in the late nineteenth century after commercialization of the electric telegraph and electrical power supply. It now covers a range of subtopics including power, electronics, control systems, signal processing and telecommunications. Electrical_engineering

| Electricity generation Electricity generation is the process of creating electricity from other forms of energy.The fundamental principles of electricity generation were discovered during the 1820's and early 1830's by the British scientist Michael Faraday. His basic method is still used todaymagnet. Electricity_generation

| Heinrich Hertz Heinrich Rudolf Hertz (February 22, 1857 – January 1, 1894) was a German physicist who clarified and expanded the electromagnetic theory of light that had been put forth by Maxwell. He was the first to satisfactorily demonstrate the existence of electromagnetic waves by building an apparatus to produce and detect VHF or UHF radio waves. Heinrich_Hertz

| Integrated circuit electronics, an integrated circuit (also known as IC, microcircuit, microchip, silicon chip, or chip) is a miniaturized electronic circuit (consisting mainly of semiconductor devices, as well as passive components) that has been manufactured in the surface of a thin substrate of semiconductor material. Integrated circuits are used in almost all electronic equipment in use Integrated_circuit

| Microelectronics Microelectronics is a subfield of electronics. Microelectronics, as the name suggests, microfabrication, of electronic components which are very small (usually micrometre-scale or smaller, but not always). These devices are made from semiconductors. Many components of normal electronic design are available in microelectronic equivalenttransistors, capacitors, inductors, resistors, diodes and of course insulators and conductors can all be found in microelectronic devices.

| Maxwell's equations In electromagnetism, Maxwell's equations are a set of four partial differential equations that describe the properties of the electric and magnetic fields and relate them to their sources, charge density and current density. These equations are used to show that light is an electromagnetic wave. Individually, the equations are known as Gauss's law, Gauss's law for magnetism, Faraday's law of induction, and Ampère's law with Maxwell's correction. Maxwell's_equations

| History of radio The pre-history and early history of radio is the history of technology that produced radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". History_of_radio

| Transistor In electronics, a transistor is a semiconductor device commonly used to amplify or switch electronic signals. A transistor is made of a solid piece of a semiconductor material, with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current flowing through another pair of terminals. Transistor

| Sound film A sound film is a motion picture with synchronized sound, or sound technologically coupled to image, as opposed to a silent film. The first known public exhibition of projected sound films took place in Paris in 1900, but decades would pass before reliable synchronization was made commercially practical. Sound_film

| Luigi Galvani Luigi Galvani (September 9 1737 – December 4 1798) was an Italian physician and physicist who lived and died in Bologna. In 1771, he discovered that the muscles of dead frogs twitched when struck by a spark. This was one of the first forays into the study of bioelectricity, a field that still today studies the electrical patterns and signals of the nervous system. He was a pioneer in modern obstetrics, and discovered that muscle and nerve cells produce electricity. Luigi_Galvani

| National Advisory Committee for Aeronautics The National Advisory Committee for Aeronautics (NACA) was a U.S. federal agency founded on March 3, 1915 to undertake, promote, and institutionalize aeronautical research. On October 1, 1958 the agency was dissolved, and its assets and personnel transferred to the newly created National Aeronautics and Space Administration (NASA). NACA was pronounced as individual letters, rather than as an acronym. National_Advisory_Committee_for_Aeronautics

| David Sarnoff David Sarnoff (, February 27, 1891 – December 12, 1971) was a Belarusian-born Russian-American businessman and pioneer of American commercial radio and television. He founded the National Broadcasting Company (NBC) and throughout most of his career he led the Radio Corporation of America (RCA) in various capacities from shortly after its founding in 1919 until his retirement in 1970.
