Semiconductor Electronics Materials Devices and Simple Circuits - Result Question 40
41. 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: 41. (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.
