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.

Text Solution

Verified by Experts

The correct Answer is:
C
lowers the potential barrier.
When we will apply forward bias to p-n junction the applied voltage is opposed by the potential barrier. Hence, the potential barrier across the junction gets reduced.
