Question

what is eleteical resistivity?

Answer 1

Electrical resistivity (also known asresistivity, specific electricalresistance, or volume resistivity) is an intrinsic property that quantifies how strongly a given material opposes the flow of electric current. A lowresistivity indicates a material that readily allows the flow of electriccurrent.

Answer 2

Electrical resistivity (also known as resistivity, specific electrical resistance, or volume 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. Low resistance metals, e.g. copper, require larger currents to produce the same amount of heat. Low resistance materials also exhibit low contact resistance
Electrical Resistivity Definition: Electrical resistivity is the measure of how much a material resists carrying an electrical current.

Electrical resistivity is denoted by the symbol ρ and has SI units of ohm meter (Ωm).
