What is a Superconductor?

A superconductor is a metal with little or no electrical resistance. When a metal usually conducts electricity, electrical energy is wasted as heat.

When metals are cooled and at the correct temperature, their resistance will decrease significantly and this will create a superconductor. With no resistance, the electrical energy is not wasted and it is therefore more efficient.

Superconductors are the transition metals which are in the middle part of the periodic
