Question

For a p–n junction diode which of the following statement is correct

(1) In forward biasing there is a diffusion and in reverse bias there is drifting of charge carriers across the junction.

(2) In forward bias there is drifting and in reverse bias there is diffusion of charge carriers across the junction.

(3) In both forward and reverse biasing the current is due to diffusion of charge carriers across the junction.

(4) In both forward and reverse bias there is current due to drifting of charge carriers across the junction.

Answer 1

Correct option: (1) In forward biasing there is a diffusion and in reverse bias there is drifting of charge carriers across the junction.
