Electrics and electronics are the domains of science and technology that deal with the study of electrons and the application of electronic devices. In the field of electronic engineering, the transistor, the integrated circuit and the semiconductor diode are the most notable devices.
Electronics deals with the design, application and management of electronic devices. It also deals with the application of electromagnetic energy to manipulate information. These devices are used in the fields of medicine, biology, oceanography and physics. The applications of electricity and electronics have expanded in the last 20 years, with the advent of the Internet.
The main objective of electronics is to control the flow of current through circuits. The device that demonstrates this feat is the transistor.
However, this was not the first device to demonstrate the ability of electrons to move in a circuit. In 1892, Hendrik Antoon Lorentz postulated the electron theory of electrical charge. This led to the development of the vacuum tube, which has been replaced by modern day semi-conductor materials naasongs.net.
A vacuum tube is a special type of electronic device that creates an electric current in a vacuum. It works like an amplifier and can be used for a variety of applications. Most of the time, vacuum tubes are found in scientific instruments and are not commonly used in consumer goods worddocx.
One of the most prominent applications of electrics and electronics is the communication of digital data among computers. This has been possible because of the technological advancements of submarine cables, land-lines and communications systems.
