Single Choice

On adjusting the P-N junction diode in forward biased:

ADepletion layer increases
BResistance increases
CBoth depletion layer and resistance decreases
Correct Answer
DNone of these

Solution

In forward biased resistance decreases, thus decreasing the depletion layer to allow maximum current to flow.
