▪ The resistivity of a material is the resistance of a wire of that material of unit length and unit cross-sectional area.

▪ The unit for resistivity is the ohm-metre.

▪ The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size.

I hope its help for you ❤

Answer:

Resistivity is defined as the resistance offered by a wire of that material of unit length and unit cross-sectional area. ... 1 ampere = 1 coulomb second-1. Current density in a conductor is defined as the current flowing through the conductor per unit cross-sectional area of that conductor.
