Consider some material that has been cooled until it has become a superconductor. If it is cooled even further its resistance will:
A) stay constant and non-zero.
B) increase.
C) decrease.
D) None of these choices.

Question

Quizplus · Accepted Answer

In a superconducting state, the material has zero electrical resistance. Cooling it further does not change this zero resistance, so none of the choices accurately describe the change in resistance.
