Superconductivity Basics-Critical Magnetic Field and Critical Temperature-Part1

Superconductivity is a phenomenon of zero resistivity below a certain temperature of a specimen. It was discovered by H. Kamerlingh Onnes in April 8, 1911 for mercury Hg where 4.2K temperature was observed at which resistivity becomes zero.

In this video lecture some basic points are defined; like critical magnetic field and critical temperature with formulation and further analysis on the basis of graphs.
