Do Metals Have Low Resistivity? Do metals have low resistivity? Metals are good electrical conductors (high conductivity and low resistivity), while non-metals are mostly poor conductors (low conductivity and high resistivity). Why do metals have low resistivity? In general, metals are good conductors. So they offer less resistance to the flow of current. Thus, metals
