Question

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.

Answer 1

When a forward bias is applied to a p−n junction, it lowers the value of potential barriers. In the case of a forward bias, the potential barrier opposes the applied voltage. Hence, the potential barrier across the junction gets reduced. Hence, (C) is the correct option.
Final Answer: (C).
