Question

what is super conductivity in electricity class 10?​

Answer 1

Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic flux fields occurring in certain materials, called superconductors, when cooled below a characteristic critical temperature. It was discovered by Dutch physicist Heike Kamerlingh Onnes on April 8, 1911, in Leiden.

Answer 2

A Superconductor is a substance of zero resistance at a very low temperature
