  • Table of Electrical Resistivity and Conductivity

     · Electrical resistivity represented by the Greek letter ρ (rho) is a measure of how strongly a material opposes the flow of electric current. The lower the resistivity the more readily the material permits the flow of electric charge. Electrical conductivity is the reciprocal quantity of resistivity. Conductivity is a measure of how well a
