E) The electrons move in Cooper pairs.

Question

Quizplus · Accepted Answer

Both the electrons in an atom and those in a superconducting ceramic are able to move without loss of kinetic energy. In the case of an atom, the electrons move in stable, circular orbits around the nucleus due to electrostatic forces. In a superconducting ceramic, the electrons move in pairs (Cooper pairs) as a result of the unique properties of the ceramic material, which allows for the flow of electricity with minimal resistance.
