What are the three components of a transistor

The base of a transistor always maintains a positive charge relative to the collector, so that holes from the collector junction cannot enter the base. And the base emitter remains in front, so holes from the emitter region enter the base and then pass through the depletion region into the collector region. Doping semiconductors were found in the three parts of the transistor. One side is the emitter and the other side is the collector. Base refers to the central area. Below is a detailed description of the three components of a transistor.

(1) Transmitter:

The job of the transmitter is to provide charge carriers to the receiver. Compared to the base, the emitter is always forward biased to provide a large number of charge carriers.

(2) According to:

The base of a transistor is the middle part, forming two PN junctions between the emitter and collector. The forward bias of the base emitter junction results in a low resistance of the emitter circuit. Due to the reverse bias of the base collector junction, the collector circuit has high resistance.

(3) Collector:

The collector is the part opposite the emitter that collects charges. When collecting, the collector always leans in the opposite direction. A transistor is equivalent to two diodes because it has two PN junctions. The emitter base diode or emitter diode is the name for the junction between the emitter and base. The junction between the collector and base is called a collector base diode or collector diode.
