Accepted Answer

BJT stands for Bipolar Junction Transistor. It is a three-layer semiconductor device used for amplification and switching.

BJT is a type of transistor that consists of three layers of semiconductor material.
It is commonly used in electronic circuits for amplification and switching purposes.
There are two types of BJT: NPN (Negative-Positive-Negative) and PNP (Positive-Negative-Positive).
BJTs have three terminals: the emitter, base, and collector.
They can be used as amplifiers to increase the strength of electrical signals.
BJTs can also be used as switches to control the flow of current in a circuit.
Example: BJT is commonly used in audio amplifiers, voltage regulators, and digital logic circuits.
