Resistivity, electrical resistance of a conductor of unit cross-sectional area and unit length. ... Resistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA/l.
