Question

A substance whose resistance becomes almost negligible at a temperature near absolute zero is called a ______.

पर्याय

• semiconductor

• superconductor

Answer 1

A substance whose resistance becomes almost negligible at a temperature near absolute zero is called a superconductor.

Explanation:

The occurrence in which specific materials demonstrate zero electrical resistance when chilled beneath a defined critical temperature is termed superconductivity. A substance that demonstrates this characteristic is referred to as a superconductor. On the other hand, semiconductors exhibit resistance that diminishes with rising temperature (unlike metals), but it remains negligible.
