Transistor Kaise Check Kren | How To Check Transistor PNP Or NPN | Transistor Test




A transistor is a small semiconductor device used to control, amplify, or switch electrical signals in electronic circuits. It is one of the most important components in modern electronics.

A transistor has three terminals:

Emitter (E)

Base (B)

Collector (C)


A small current applied to the base controls a larger current flowing between the collector and emitter.
Because of this property, transistors can act as:

1. Amplifiers

Increase weak electrical signals (used in radios, speakers, audio circuits).

2. Switches

Turn electronic devices ON or OFF (used in computers, power supplies, digital circuits).
