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

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

detailed solution

Correct option is D

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.
