NEET 2022 Physics Temperature Dependence of Resistance MCQ Question
Type: MCQ-conceptual-Medium-Class 12
As the temperature increases, the electrical resistance:
A
increases for conductors but decreases for semiconductors
B
decreases for conductors but increases for semiconductors
C
increases for both conductors and semiconductors
D
decreases for both conductors and semiconductors
Correct Answer
Option A
Detailed Explanation
For conductors, resistance increases with temperature due to increased lattice vibrations. For semiconductors, resistance decreases as more charge carriers are available.
