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

  1. affects only reverse resistance.
  2. affects only forward resistance.
  3. does not affect resistance of p-n junction.
  4. affects the overall V-I characteristics of p-n junction.

Correct answer · Option 4

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

Explanation

Heating increases thermally generated minority carriers, thereby altering the reverse saturation current and shifting the overall V-I characteristics of the p-n junction.
