NEET Physics Resistance & Resistivity Assertion Reason Question
Assertion (A): The resistivity of a material does not change when the length and cross-sectional area of the wire are altered.
Reason (R): Resistivity is an intrinsic property of the material and is independent of the dimensions of the conductor.
Both A and R are true, and R is the correct explanation of A.
Both A and R are true, but R is not the correct explanation of A.
A is true but R is false.
A is false but R is true.
Correct Answer
Detailed Explanation
Resistivity is a characteristic of the material itself and does not depend on its shape or size. This is consistent with the NCERT explanation that resistivity is an intrinsic property.
