conductor Substance or object that allows easy passage of free electrons. Conductors have low electrical resistance that opposes the flow. Metals, the best conductors, have free electrons that become an electric current when moved. The resistance of metal conductors increases with temperature because the lattice vibrations of atoms increase and scatter the free electrons.
