A Superconductor is a material that can conduct electricity or transport electrons from one atom to another with no resistance. This means no heat, sound or any other form of energy would be released from the material when it has reached "critical temperature" (Tc), or the temperature at which the material becomes superconductive.

Superconductivity is  a phenomenon of exactly zero electric resistance and expulsion of magnetic  fields occuring in certain materials when cooled below a characteristisc critical temperarture .it was discovered by dutch physicst heike kamelingh onnes on april 8 1911 in leiden
