Super conductor will have zero resistance or zero resistivity. This happens when the temperature of the conductor reaches a very low temperature known as critical super conducting transition temperature. In case of Mercury it will be 4.2K.
Any electrons flowing through a superconductor will show up as a regular electric 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.
motion
A superconductor superconducts ONLY at extremely low temperature.
Yes, a superconductor has zero resistance.
An ideal superconductor has exactly zero losses, thus resistance is zero.
