Single Choice

If the forward voltage in a semiconductor is doubled, the width of depletion layer will

Abecome half
Correct Answer
Bbecome one-fourth
Cremain unchanged
Dbecome double

Solution

P-N junction -

When P type semiconductor is mixed with N - type semiconductor, P-N junction formed

Wherein

There is very thin region (of the order of micro meter) called depution region.

width of depletion region $$\propto \dfrac{1}{V}$$

V=Applied potential

i.e. If V is doubled width of depletion region will become half.
