Question

Q. 1 Resistivity is the property
depends upon
of
and it
Substance and​

Answer 1

Answer:

here is your answer. pls mark as brainliest and like also.

Explanation:

Resistance of a conductor depends on length, thickness, nature of material and temperature of the conductor; while resistivity of a substance depends on the nature of the substance and temperature. (d) Resistivity of a substance depends on the nature of the substance and its temperature.

Answer 2

Answer: temperature

Explanation:

Electrical resistivity is an intrinsic property that quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. It is defined as the resistance per unit length of the resisting material.

At high temperatures, the resistance of a metal increases linearly with temperature. As the temperature of a metal is reduced, the temperature dependence of resistivity follows a power law function of temperature.

Hence, resistivity is dependent on the temperature.
