Question

Define resistivity of a material. Give it's SI unit.

Answer 1

A low resistivity indicates a materialthat 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). ... Its SI unit is siemens per metre (S/m) and CGSEunit is reciprocal second (s−1).
