Vedclass · Answer

(A) Resistivity $(\rho)$ is an intrinsic property of a material. It depends only on the nature of the material and the temperature. It does not depend on the physical dimensions (length, area of cross-section) or the shape of the resistor. Therefore, if the shape of the resistor is changed, the resistance $(R)$ will change, but the resistivity $(\rho)$ remains constant.

The resistivity of a material does not change if:
