The electrical resistivity of a material is defined as the resistance offered to current flow by a conductor of unit length having unit area of cross section
The unit of ρ is ohm−m(Ωm)

Electrical resistivity is the reciprocal of electrical conductivity. It is the measure of the ability of a material to oppose the flow of current. Materials resist the flow of electric current. Some of the materials are better at conducting electric current than the others.
Resistivity is defined as the electrical resistance of a conductor of unit cross-sectional area and unit length. The resistance of any conductor is directly proportional to the length of the conductor and inversely proportional to the area of cross-section of the conductor.
