What is the working of transistor

Question

Accepted Answer

A transistor is a semiconductor device that amplifies or switches electronic signals and electrical power.

Transistors are made up of three layers of semiconductor material: the emitter, base, and collector.
They can be used as amplifiers to increase the strength of a weak signal.
Transistors can also be used as switches to control the flow of current.
They are commonly used in electronic devices such as radios, televisions, and computers.
Examples of transistors include bipolar junction transistors (BJTs) and field-effect transistors (FETs).
