48. In forward bias, the width of potential barrier in a $p-n$ junction diode
(a) increases
(b) decreases
(c) remains constant
(d) first ’ $1$ ’ then ’ $2$ '
Show Answer
Answer:
Correct Answer: 48.(b)
Solution:
- (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.
