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

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

Correct answer: Affects the overall V-I characteristics of p-n junction

Solution

Temperature changes affect the overall V-I characteristics of a p-n junction diode because both forward and reverse resistances are influenced by temperature, altering the current flow.
