Question

The increase in the width of the depletion region in a $\text{p-n}$ junction diode is due to :

• A. both forward and reversed bias
• B. increase in forward current
• C. forward bias only
• D. reverse bias only

Answer 1

The correct option is D reverse bias only

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 in a diode.

Hence, option (d) is correct answer.
