A superconductor is a material with extremely low resistance to an electrical current. Many are metals or the like which have been supercooled to temperatures approaching absolute zero.
Examples are Mercury, lead and tin
An example of a superconductor is mercury. Superconductivity is an element's ability to have no electrical resistance when cooled to temperatures close to absolute zero.
A conductor is a substance that either conducts electricity or allows it to pass through it. Iron (or any metal) is an example of a conductor because you can transmit electricity through it.

A superconductor.
Not used today but possible in the future: - carbon nanotubes - doped carbon as CaC6
Currently, the superconductor with the highest critical temperature ever recorded is Mercury Barium Thallium Copper Oxide or Hg0.2Tl0.8Ca2Cu3O, which has a critical temperature of 139 K at one atmosphere. This superconductor is a type of ceramic copper oxide and its critical temperature was determined in 1995 by Chakoumakos, Dai, Wong, Sun, Lu, and Xin. Apparently, metal-copper oxide ceramic superconductors have high critical temperatures, which might unlock the key of synthesizing a high temperature superconductor that is superconductive under room temperature conditions.
Electrical conductivity is 6.7 Ms/m (mega-siemens / metre) which is approximately the same as 1010 carbon steel. Technetium, cooled to a few degrees above absolute zero, becomes a superconductor. Please see the links.
Copper has a conductivity of 57 MS/m, whereas Silver has a conductivity of 66.5 MS/m. Bosch Automotive Engineer's Handbook 2nd Ed. 1987 Delta Press ISBN:1-85-226-00-9
Water is not a superconductor.
Pure mercury will exhibit superconductivity at 4.2 degrees Kelvin. It was the first superconductive material that H. Kamerlingh Onnes found in 1911.
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.
