Question

What is super conductivity?

✓

Answer

$1.$ The resistivity of a metal decreases as the temperature decreases.
$2.$ In case of some metals and metal alloys, the resistivity suddenly drops to zero at a particular temperature $(T_c),$ this temperature is called critical temperature.
$3.$ Super conductivity is the phenomenon where resistivity of a material becomes zero at particular temperature.
$4.$ For example, mercury loses its resistance completely to zero at $4.2 K.$
