A current of electricity can flow at the same strength for an indefinitely long time in a superconductor but only for as long as the superconductor is held below its critical temperature.
If its temperature were allowed to rise to its critical temperature - or higher - the material would no longer behave as a superconductor: it would acquire resistivity which would restrict the flow of current.
Water is not a superconductor.
American Superconductor was created in 1987.
No. Salt water is a conductor but not a superconductor.
Low temperature. A superconductor doesn't 'perform' at all, and isn't even a superconductor, above its critical temperature.
Yes, a superconductor has zero resistance.
A superconductor superconducts ONLY at extremely low temperature.
An ideal superconductor has exactly zero losses, thus resistance is zero.
