To use a transistor as an amplifier

A

the emitter base junction is forward based and the base collector junction is reverse biased

B

no bias voltage are required

C

both junctions are forward biased

D

both junctions are reverse biased

Text Solution

Verified by Experts

The correct Answer is:
A

This is general configuration, emitter is forward biased and collector is reverse biased w.r.t. the base.
