In superconductivity, the electrical resistance of material becomes?
Zero
Infinite
Finite
All of the above
As we have learnt,
Superconductivity
Kammerlingh Onnes observed this phenomenon at 4 K in mercury. A substance is said to be superconducting when it offers no resistance to the flow of electricity. There is no substance which is superconducting at room temperature. Superconductors are widely used in electronic power transmission, building super magnets etc. For example, YBa2Cu3O7, Nb3Ge alloy, (TMTSF)2PF6, etc.
-
Superconductors are those materials which have zero electrical resistance or infinite conductance.
Their conductivity is known as superconductivity.
Option (a) is correct
