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

  • Affects only reverse resistance

  • Affects only forward resistance

  • Affects the overall V - I characteristics of p-n junction

  • Does not affect resistance of p-n junction

Answer

C.

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

On heating, a number of electron-hole pairs increases, so overall resistance of diode will change.

Hence, forward biasing and reversed biasing both are changed.
