Question

At equilibrium, in a p-n junction diode the net current is
A) due to diffusion of majority charge carriers.
(B)
due to drift of minority charge carriers.
(C)
zero as diffusion and drift currents are equal and opposite
(D)
zero as no charge carriers cross the junction.
​

Answer 1

Answer:

(c) zero as diffusion and drift currents are equal and apposite

Answer 2

Answer:

D

Explanation:

At equilibrium there is no net current flowing because diffusion and drift current are opposite to each other and equal in amount.
