Physics-Resistance & Resistivity
NEET Physics Resistance & Resistivity Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): The resistance of a conductor increases with increase in temperature. | Reason (R): The resistivity of metals typically increases with temperature due to increased scattering of conduction electrons.
A
Both A and R are true and R is the correct explanation of A.
B
Both A and R are true but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Correct Answer
Option A
Detailed Explanation
The resistivity of metals increases with temperature because the atomic lattice vibrations increase, causing more scattering of conduction electrons. This leads to an increase in resistance.
