A material is said to be a superconductor if when it is brought down to a critical low temperature it loses its resistivity completely.

<><><>

A superconductor is a material that has zero electrical resistance at certain temperatures. For example, in a ring of superconducting material, if you induce a current to flow in a circle, it will continue flowing for ever. So far, it has only been possible to create superconductors at cryogenic (i.e., "supercold") temperatures.

<><><>

Superconductivity is a property of a substance at a given temperature, not of a substance at any temperature.

Superconductors are things that have no electrical resistance when they are at low enough temperatures, typically close to absolute zero i.e. 0 Kelvin or about -273 degrees C.

There are also 'high-temperature' superconductors that operate at about 70 degrees K (-203 degrees C).

We haven't yet found a substance that works as a superconductor at room temperature there is a lot of research on-going. The aim is to try to find metal alloys or other substances that will behave as superconductors at temperatures which are much closer to room temperature than to absolute zero i.e. 0 Kelvin or about -273 degrees C.

Superconductivity is the flow of electric current without resistance in certain metals, alloys, and ceramics at temperatures near absolute zero, and in some cases at temperatures a considerable amount above absolute zero.

Superconducitivity is the concept of an electric current traveling through a conductor without electrical resistance. This conductor is the superconductor which usually exists at very low temperatures. The first superconductor was discovered by Onnes in 1910s at about 4 degrees K. Superconductors have some very special characteristics which are very beneficial once scientists found a way to manipulate the structures of those conductors to achieve superconductivity at room temperature.
