NEET 2018 Physics p-n Junction MCQ Question
Type: MCQ-conceptual-Medium-Class 12
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.
Correct Answer
Option D
Detailed Explanation
Temperature changes affect the carrier concentration in a semiconductor, which in turn affects both forward and reverse resistances, altering the V⁻I characteristics.
