Semiconductor Electronics Materials Devices and Simple Circuits - Result Question 4
4. In a p-n junction diode, change in temperature due to heating
[2018]
(a) Affects only reverse resistance
(b) Affects only forward resistance
(c) Affects the overall V-I characteristics of p-n junction
(d) Does not affect resistance of p-n junction
Show Answer
Answer:
Correct Answer: 4. (c)
Solution:
- (c) On heating, number of electron-hole pairs increases, so overall resistance of diode will change.
Hence forward biasing and reversed biasing both are changed.
