Question:

The resistivity of a material depends on

Options:

length, area of cross section and temperature of material

length and area of cross section of material

nature and temperature of material

temperature of material only

Correct Answer:

nature and temperature of material

Explanation:

The correct answer is Option (3) → nature and temperature of material

Resistivity ($\rho$) is a material property that depends on the nature of the material and its temperature. It does not depend on the length or cross-sectional area, which affect resistance but not resistivity.

Answer: nature and temperature of material
