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

In a p-n junction diode, change in temperature due to heating
  1. does not affect resistance of p-n junction
  2. affects only forward resistance
  3. affects only reverse resistance
  4. affects the overall V-I characteristics of p-n junction

Solution

Due to heating, the number of electron-hole pairs will increase, so overall resistance of diode will change. Due to which forward and reverse biasing both are changed. Hence, in a PN junction diode, change in temperature due to heating affects the overall V-I characteristics of PN junction
