![]() ![]() ![]() In this aspect, it can be used as an amplifier. There are two configurations for this, either PNP or NPN with the middle material acting as the base or flow control.Ī very small change in the current or voltage in the middle base layer results in a large amount of electricity flowing through the whole component. Transistors are created through a chemical process known as doping, where the semiconductive material either gains an extra negative charge (N-type) or extra positive charge (P-type). The base or middle of the transistor acts as the real switch control electrode through which electron stimulation rapidly changes the material from an insulator to conductive state, thereby allowing the flow of electricity. The most basic function of a transistor is as an electronic switch, which allows electrons to flow from its collector side out through the emitter side. physicsan object that controls the flow of electricity inside a piece of electronic equipment such as a radio or. In this video i will discuss What is a Transistor Definition, Function & Uses. Their achievement is responsible for such modern appliances as wide screen TVs, smartphones, tablets and other electronic computing devices. It can work either as an amplifier or a switch: When it works as an amplifier, it takes in a tiny electric current at one end (an input current) and produces a much bigger electric current (an output current) at the other. ![]() It was invented in 1947 by William Shockley, Walter Brattain and John Bardeen, who were jointly awarded the Nobel Prize in Physics for catapulting technological development. A transistor is a miniature electronic component that can do two different jobs. The transistor is composed of a semiconductive material, usually silicon, and at least three terminals for connecting to the external circuit. ![]()
