In this sense, electrical engineering is the branch dealing with “heavy current”—that is, electric light and power systems and apparatuses—whereas electronics engineering deals with such “light current” applications as telephone and radio communication, computers, radar, and automatic control systems. Many of these devices are also widely used in shipping. Mechanical engineering has been around in the ancient Greece and China. The functions performed by electrical and electronics engineers include (1) basic research in physics, other sciences, and applied mathematics in order to extend knowledge applicable to the field of electronics, (2) applied research based on the findings of basic research and directed at discovering new applications and principles of operation, (3) development of new materials, devices, assemblies, and systems suitable for existing or proposed product lines, (4) design of devices, equipment, and systems for manufacture, (5) field-testing of equipment and systems, (6) establishment of quality control standards to be observed in manufacture, (7) supervision of manufacture and production testing, (8) postproduction assessment of performance, maintenance, and repair, and (9) engineering management, or the direction of research, development, engineering, manufacture, and marketing and sales. For example, in the high-voltage transmission of electric power, large arrays of electronic devices are used to convert transmission-line current at power levels in the tens of megawatts. Another field is the application of computers and radio systems to automobiles, ships, and other vehicles. The word engineer comes from a Latin word meaning ‘cleverness’. It is possible for the people to have the household object in cheaper price due to the invention of both items. One of the most active areas is the development of new electronic devices, particularly the integrated circuits used in computers and other digital systems. However, engineers whose work is related exclusively to computer hardware are considered computer hardware engineers. Around 220 million tons of old computers and other electronic devices are disposed in the United States each year. ( Source) 2. Facts about Engineering. Consulting engineers, specializing in new fields, are employed to study and recommend courses of action. Alexander Graham Bell, inventor who patented the telephone in 1876, lecturing at Salem, Massachusetts (top), while friends in his study at Boston listen to his lecture via telephone, February 12, 1877. In 1887 the German physicist Heinrich Hertz fulfilled Maxwell’s prediction by experimentally producing radio waves. Took me a while to really grasp certain elements of electronics, I still probably would fail any test. In the high-technology industries typical of modern electronics, an engineering background at not less than the bachelor’s level is required to assess competitive factors in sales engineering to guide marketing strategy. Electronics engineers design, develop, test, and supervise the manufacture of electronic equipment, such as broadcast and communications systems. The electrical engineering aspect of the discipline includes designing application devices, interface hardware, memories, and computer chips. The functions performed by electrical and electronics engineers include (1) basic research in physics, other sciences, and applied mathematics in order to extend knowledge applicable to the field of electronics, (2) applied research based on the findings of basic research and directed at discovering new applications and principles of operation, (3) development of new materials, devices, assemblies, and … Author of.

Fact 1: The frequencyof the analog circuit is often measured or controlled in analog signal processing. The electronics industry dates to the 1800s, when scientists first discovered that they could pass electricity through gas from one metal electrode to another. Analog circuits are used for signals that have a range of amplitudes. IEEE. Engineering comes from the Latin word which means ‘cleverness’. The educational background required for these functions tends to be highest in basic and applied research. Omissions? Hendrik Antoon Lorentz of the Netherlands postulated the electron theory of electrical charge in 1892, and in 1897 J.J. Thomson of England showed that thermionic emission was indeed caused by negatively charged particles (electrons). The most noteworthy pioneers include Ludwig Wilhelm Gilbert and Georg Simon Ohm of Germany, Hans Christian Ørsted of Denmark, André-Marie Ampère of France, Alessandro Volta of Italy, Joseph Henry of the United States, and Michael Faraday of England. Let us know if you have suggestions to improve this article (requires login). Electronics engineering is that branch of electrical engineering concerned with the uses of the electromagnetic spectrum and with the application of such electronic devices as integrated circuits and transistors. Moreover, in the regulation and control of interconnected power systems, electronic computers are used to compute requirements much more rapidly and accurately than is possible by manual methods. The world today is entirely dependent on science to survive. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox.
