What is mean by electrical resistivity of an material

1.	What is mean by electrical resistivity of an material
Answer» Resistivity is the measure of a material’s ability to oppose the flow of current . Resistivity of a conductor is a property of the material of the conductor. Unit of resistivity is Ohm meter, Ω m . Resistivity of the material of the conductor changes with temperature. Resistivity of copper is 1.7 × 10 -8 Ω m at room temperature. There is nothing called resistivity of a circuit.
