Question
CBSEENPH12038762

State True or False:

When a forward bias is applied to a p-n junction, it

A.

Raises the potential barrier.

B.

Reduces the majority carrier current to zero.

C.

Lowers the potential barrier.

D.

None of the above.

Solution
A. FALSE
B. FALSE
C. TRUE
D. FALSE
When a forward bias is applied across the p-n junction, the applied voltage opposes the barrier voltage. Due to it, the potential barrier across the junction is lowered. Hence answer (c) is correct.
