Answer:
Correct option is
D
temperature
Answer is D.
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.
