Define resistivity & its unit?​

Answer 1

Explanation:

Electrical resistivity is a physical attriibute of a material that defines how much it opposes the flow of electric current through itself. It is the electrical resistance per unit length and per unit of cross-sectional area of any material, at a given temperature.

The SI unit of electricalresistivity is the ohm⋅metre (Ω⋅m). It is commonly represented by the Greek letter ρ, rho.

Answer 2

$\huge\mathcal\pink{ANSWER}$

It is a measure of the resisting power of a specified material to the flow of an electric current.

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