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

Solution

## 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.Chemistry
