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

A

does not affect resistance of p-n jucntion

B

affect only forward resistance

C

affects only reverse resistance

D

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

Text Solution

Verified by Experts

The correct Answer is:
D
When temperature increseas due to heating then new electron- hole pairs are created hence changes resistance of the diode and thus it affects overal V- I chracteristic of diode hence option (d) is correct .
