Superconductivity and Applications

Superconductivity is the ability of certain materials to conduct electric current with practically zero resistance. This capacity produces interesting and potentially useful effects. For a material to behave as a superconductor, low temperatures are required. Superconductivity was first observed in 1911 by H. K.

Thus super-conductor are those material conductors whose resistance disappear at critical temperature. The critacal temperautre is different materials. Super conductors are used (i) in power transmission (ii) to produce very high speed computers.
