Physics Question on Semiconductor electronics: materials, devices and simple circuits

In a pnp-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

Answer

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

Explanation

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.
