Question

what is meant by resistivity​

Answer 1

Answer:

Resistivity is defined as the resistance offered by the material per unit length for unit cross-section. The SI unit of resistivity is Ohm. meter. Resistivity increases linearly with temperature. The resistivity of conductors is low when compared to the resistivity of the insulators.

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.
