The main uses and functions of transistors

The structure of a transistor includes an emitter, a base, and a collector. The emitter and collector are high inclusion regions, while the base is low inclusion regions. If a certain voltage is added at the base extreme, the current between the emitter and collector will change, thus achieving the operation of the power supply. This article will introduce the application scope and functions of the transistor.
