Question

In forward bias, the width of potential barrier in a p-n junction diode

Answer 1

juction diode is correct

Answer 2

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:-. C

Explanation-

When a forward bias voltage is applied, The N-region is attached to the negative terminal of the battery and the P-region is connected to the positive terminal of the battery. Negative-negative and positive-positive repulsion occur on both sides, so it opposes the junction barrier voltage, hence the barrier voltage is reduced/lowered.
