An electrical conductor that has very low resistance to current at low temperatures is called?

Answer 1

You're going for "superconductor", but your appreciation of the phenomenon

of superconductivity is fundamentally wrong, and your description is incorrect.

A superconductor is not a substance that has very low resistance at low temperature.

It's a substance that at sufficiently low temperature loses all resistance, and its

resistance becomes zero. Just plain zero.

Once an electric current is circulating in a superconducting loop and the ends of the

loop are connected together, the current keeps on circulating without any batteries

or power supply as long as the loop stays cold enough. That can be days, or weeks,

or months, during which time the current travels around the entire loop literally millions

of times, without additional input and without loss.

Answer 2

A superconductor is an electrical conductor that has very low resistance to current at low temperatures, usually close to absolute zero. This phenomenon allows for the efficient transfer of electricity without any energy loss due to resistance.
