In forward bias, the width of potential barrier in a p-n junction diode

1. increases
2. decreases
3. remains constant
4. first ‘1’ then ‘2’

Correct Option: B

We know that in forward bias of p-n junction diode, when positive terminal is connected to p-type diode, the repulsion of holes takes place which decreases the width of potential barrier by striking the combination of holes and electrons.
