The temperature below which the resistivity of a superconductor falls to zero is called
Correct answer: D. Critical temperature
- A. Absolute temperature
- B. Kelvin temperature
- C. Limiting temperature
- D. Critical temperature
Explanation
The temperature below which the resistivity of a superconductor falls to zero is called the critical temperature or transition temperature, often denoted as Tc. Below this temperature, the material exhibits zero electrical resistance, becoming a superconductor. Above Tc the material behaves as a normal conductor.

About Electrical Properties of Solids
Electrical properties of solids depend on their band structure, charge carriers and conductivity. The topic compares conductors, insulators and semiconductors, relates resistivity to temperature, and covers intrinsic and extrinsic semiconductors, donor and acceptor impurities, electron and hole conduction, and the formation of p-type and n-type materials.
