Question

Define resistivity.​

Answer 1

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

Answer:

Resistivity or specific resistance is resistance of a conducting material of unit length and having unit area of cross section. It is a property of material and depends on nature of material. SI unit is Ohm-m (Ω.m).
