Question

at equilibrium in a p-n junction diode the net current is?
( give the correct option)
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

☆Your answers is option no (c) zero as diffusion and drift currents are equal and opposite

• it happen because
• At equilibrium the p_n junction has the same number of majority and minority carriers moving
• in a opposite direction
