Question

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

(a) electric field is zero

(b) potential is maximum

(c) electric field is maximum

(d) potential is zero

Answer 1

Correct Option (a) electric field is zero

Explanation:

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.
