Q91NEET 2018Medium

P-N Junction Diode

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

Show answer and solution

Answer: (d)

  1. Heating generates more electron-hole pairs: reverse (minority) current increases.
  2. Barrier potential falls, so forward current rises at the same voltage (forward resistance changes too).
  3. Both regions change, so the whole V-I characteristic is affected: the answer is (d).
