How does resistance relate to conductivity? Physics Electrical Energy and Current Current and Resistance 1 Answer Aritra G. May 30, 2015 Resistance #R# of a wire is given by : #R = rho*l/A# where #l# is the length of the wire and #A#, its area of cross section. #rho# is a constant for the given material at a particular temperature. It is called to resistivity or specific resistance of the material. The conductivity (#sigma#) is defined as, #sigma = 1/rho # Answer link Related questions When work is done on a positive test charge by an external force to move it from one location to...
