In normal transistor operation

A

emitter -base junction and collector-base junction are both in reverse bias

B

emitter -base junction is in forward bias and collector -base junction is in reverse bias

C

emitter-base junction and collector-base junction both are in forward bias

D

emitter-base junction is in reverse bias and collector -base junction is in forward bias

Text Solution

Verified by Experts

The correct Answer is:
B
In common-base (CB) mode of a transistor the emitter base junction is kept at forward bias keeping the base grounded and the collector -base junction is kept at reverse bias to get the proper circuit action.
