$\huge\bf\mathscr\pink{Your\: Answer}$

♠ What is Resistivity ??

♥Electrical resistivity is a fundamental property of a material that quantifies how strongly that material opposes the flow of electric current.

♠ Units of Resistivity

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

♠ Formula of Resistivity

♥ ρ = R × A/l

where,

ρ = Resistivity of that material

R = Resistance of the material

A = Area of cross section for which its to be calculated

l = length for which it is to be calculated

♠ Factors on which Resistivity depends

♥  The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size.
