Question

what is resistivity of a material?

Answer 1

Electrical resistivity (also known as resistivity, specific electrical resistance, orvolume resistivity) is a measure of how strongly a material opposes the flow ofelectric current. A low resistivity indicates a material that readily allows the movement of electric charge. The SI unit of electrical resistivity is the ohm metre [Ω m].

Answer 2

Electrical resistivity  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. Resistivity is commonly represented by the Greek letter ρ (rho)
