In the middle of the depletion layer of ...

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

A

electric field is zero

B

potential is zero

C

potential is maximum

D

electric field is maximum

Text Solution

Verified by Experts

The correct Answer is:
a

When a n junction is reverse biased, the width of the depletion layer becomes large and so the electric field (E = v/d) becomes very small, nearly zero.
