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:

  1. (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.
