The property of matter when it displays zero resistance to the flow of electric current is called superconductivity. Superconductivity undertakes extraordinary capabilities for electric circuits. If conductor resistance could be eliminated completely, there would be no inefficiencies in electric power systems due to stray resistances. Electric motors could be made almost perfectly efficient. The ideal characteristics of components like capacitors and inductors are normally ruined by inherent wire resistances, could be made ideal in a practical sense.
