Resistivity is the property of the conductor due to which it offersresistance to the flow of current through it . It is measured by theresistance offered by 1m length of wire of that material of area of cross section 1 m2. Resistivity of the material depends only on its material and temperature.

1)resistance will not constant always but
resistivity will constant always.
2)Electrical resistivity is a fundamental property of a material that quantifies how strongly that material opposes the flow of electric current. A low resistivity indicates a material that readily allows the flow of electric current. Resistivity is commonly represented by the Greek letter ρ.
3)The electrical resistance of an object is a measure of its opposition to the flow of electric current. The inverse quantity is electrical conductance, and is the ease with which an electric current passes. Electrical resistance shares some conceptual parallels with the notion of mechanical friction.
