Answer 2

Answer:

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.
