Question

what do you mean by resistivity?​

Answer 1

Explanation:

Resistivity. ... Resistivity, electrical resistance of a conductor of unit cross-sectional area and unit length. A characteristic property of each material, resistivity is useful in comparing various materials on the basis of their ability to conduct electric currents. High resistivity designates poor conductors.

Answer 2

Resistivity is defined as the resistance offered by a wire of that material of unit length and unit cross-sectional area. resistivity , ρ = R A/l. R - resistance of a conductor.

Resistance is the physical property of a substance because of which it opposes the flow of current i.e. electrons. Resistivity is the physical property of a particular substance which is having particular dimensions.

Resistivity is only proportional to the nature and temperature of the particular material.
