Question

The increase in the width of the depletion region in a p-n junction diode is due to :

(1) increase in forward current

(2) forward bias only

(3) reverse bias only

(4) both forward bias and reverse bias

Answer 1

Ans : (3) reverse bias only

Explanation :

The increase in the width of the depletion region is due to the absence of the electrons and holes in the region.

This occurs only in the case of the reverse bias only in a diode.
