Question

Define electrical resistivity. Write its SI unit.​

Answer 1

Answer:

Electrical resistivity and its inverse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts electric current. A low resistivity indicates a material that readily allows electric current. Resistivity is commonly represented by the Greek letter ρ.(rho)

SI unit of electrical resistivity is the ohm-meter (Ω⋅m)
