Question

Define resistivity of a conductor. Write its S. I unit.​

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.

S.I unit of resistivity of a conductor is ohm-meter

(Ω⋅m)
