Unbiased and Biased Transistor

When no external supply is connected to a transistor then the transistor is in unbiased condition and if external supply is connected to a transistor then the transistor is in biased condition.

This video will help you ti understand the working of unbiased and biased transistor.


A transistor is a semiconductor device used to amplify electronic signals. It is composed of semiconductor material usually with at least three terminals for connection to an external circuit.
