Solution Verified by Toppr

Correct option is A)

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 ∝

V 1 V=Applied potential

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