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

Options

  1. Adoes not affect resistance of p-n junction
  2. Baffects only forward resistance
  3. Caffects only reverse resistance
  4. Daffects the overall V-I characteristics of p-n junction

Correct answer

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

Step-by-step 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
