Question

The substance whose resistance gets reduced to virtually zero at very low temperature is called

• A. electrical conductor
• B. hyper-conductor
• C. superconductor
• D. insulator

Answer 1

The correct option is C superconductor

$\text{Substance whose resistance gets reduced to virtually zero at a very low temperature is called a}superconductor.$

A superconductor is a material that can conduct electricity or transport electrons from one atom to another with no resistance. In a superconductor, the resistance drops abruptly to zero when the material is cooled below its critical temperature. An electric current flowing through a loop of superconducting wire can persist indefinitely with no power source.

Option C is correct.
