A `p-n-p` transistor is said to be in active region of operation, When

A

both emitter junction and collector junction are forward biased

B

both emitter junction and collector junction are reverse biased

C

emitter junction is forward biased and collector junction is reverse biased

D

emitter junction is reverse biased and collector junction is forward biased

Text Solution

Verified by Experts

The correct Answer is:
C
For amplification of p-n-p transistor, emitter junction is forward biased and collector junction is reverse biased. In this state, p-n-p transistor is said to be in active region of operation.
