Answer 1

Answer:

Electrical resistivity is an intrinsic property that quantifies how strongly a given material opposes the flow of electric current. A low resistivity indicates a material that readily allows the movement of electric charge. That is, the number or density of free electrons in the conductor which the nature of the conductor.
