Question

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.

Answer 1

(a) electric field is zero

When a p – 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.
