Materials exhibiting zero value of resistivity are known as ____________ ?
Correct answer: D. superconductors
- A. conductors
- B. semiconductors
- C. insulators
- D. superconductors
Explanation
A superconductor has zero electrical resistivity below its critical temperature, so it can carry current without ohmic power loss. Ordinary conductors have low resistivity, but not exactly zero.
