In the middle of the depletion layer of ...

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

A

electric field is zero

B

potential is maximum

C

electric field is maximum

D

potential is zero

Text Solution

Verified by Experts

The correct Answer is:
A
Due to the reverse biasing, the width of depletion region increases and current flowing through the diode is almost zero. In this case electric field is almost zero at the middle of the depletion region.
