P-N junction diode

Question

In a p-n junction diode, change in temperature due to heating

Easy

A

affects only reverse resistance
B

affects only forward resistance
C

does not affect resistance of p-n junction
D

affects the overall V-I characteristics of p-n junction

Solution

Due to heating, number of electron-hole pairs will increase, so overall resistance of diode will change. Due to which forward biasing and reversed biasing both are changed.
