Physics-Resistance & Resistivity
NEET Physics Resistance & Resistivity Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): The resistivity of metals increases with an increase in temperature. | Reason (R): In metals, the average time between electron collisions decreases with an increase in temperature.
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 average time between electron collisions decreases, leading to more frequent collisions.
