Question

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

• A. affects only reverse resistance
• B. affects only forward resistance
• C. does not affect resistance of p-n junction
• D. affects the overall V -I characteristics of p-n junction

Answer 1

Answer: (D)

Due to heating, number of electron-hole pairs will increase, so overall resistance of diode will change.
Due to which forward biasing and reversed biasing both are changed.
