In the middle of the depletion layer of a reverse - biased `p - n ` junction , the

Options

A. potential is zero
B. electric field is maximum
C. potential is maximum
D. electric field is very very small

Answer

D

Explanation

When the p-njunction is reversed biased, the width of the depletion region becomes very large and hence the electric field `[E=V/d]` becomes very small.
In forward bias , `E="dV"/"dx"` is very large
