Question

define electrical resistivity and give its units

Answer 1

if we have a conductor of length 1 m and it's area of cross section is 1m2 than the resistance of a conductor is called resistivity or specific heat

Answer 2

Resistivity definition: ... The electrical resistivity is the electrical resistance perunit length and per unit of cross-sectional area at a specified temperature. The SIunit of electrical resistivity is the ohm⋅metre (Ω⋅m). It is commonly represented bythe Greek letter ρ, rho.
