Question

what is superconductor?

Answer 1

the substances who have zero resistivity even at super low temperature are known as super conductor
eg fullerenes

Answer 2

What is conductor?

Answer:- Conductors are the substance which allows electricity to p@ss through them.

SuperConductors :-

_______________________

• A superconductor is substance of zero resistance at a very low temperature.
• Some of the substance like Tin , lead etc are known to be superconductor.
• they have a property of decreasing tremendously, the decrease in temperature and becomes almost zero in the low temperature range near absolute zero.
• This means of super contractor is something which has a zero resistance.
• Once a current start flowing in superconductor it persists even when there is no potential difference across it.

Some facts about superconductors:-

• Super conductor are not in common use since it is very difficult to achieve such a low temperature.
• the size of computers could then be reduced to a few canteen if the wire should be made of super conductors.
