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

Answer»

WIDENS the depletion zone.
increases the potential difference across the depletion zone.
increases the number of donars on the n-side.
increases the electric field in the depletion zone.

Solution :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.
