Statement-I : To be used as amplifier, the transistor in the common emitter confuration is preferred to the common base configuration.
Statement-II : In the common emitter, the signal is applied between emitter and base.

A

If both assertion and reason are true and the reason is the correct explanation of the assertion

B

If both assertion and reason are true but the reason is not the correct explanation of the assertion

D

If both assertion and reason are false statement

Text Solution

Verified by Experts

The correct Answer is:
2
The common emitter configuration (CE) provides maximum voltage and current gain.
The other configuration provide either high current gain or voltage gain but not both for a BJT.
