Application of a forward bias to a p-n junction ………

Options

A. widens the depletion zone.
B. increases the potential difference across the depletion zone.
C. increases the number of donars on the n-side.
D. increases the electric field in the depletion zone.

Answer

C

Explanation

increases the number of donars on the n-side.

The number of donor will be higher as the electrons move from negative terminal to the n-side and the number of pentavalent ions decreases. Hence potential barrier also decreased. The neutral pentavalent atom will give electron again.
