Question

What is electrical resistivity of a meterial

Answer 1

Electrical resistivity (also known as specific electrical resistance, or volume 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(rho). The SI unit of electrical resistivity is the ohm-metre (Ω⋅m).[1][2][3] As an example, if a 1 m × 1 m × 1 m solid cube of material has sheet contacts on two opposite faces, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m.
