Answer to Question #15401 in Electric Circuits for liam riley

Question

Ok at absolute zero everything stops right but how can a superconductor have persistent current passing through when everything is meant to stop surely the electrons would stop but that defeats the purpose of superconductivty

Answer 1

Superconductivity is a phenomenon of exactly zero electrical resistance and expulsion of magnetic fields occurring in certain materials when cooled below a characteristic critical temperature (nearly absolute zero). Your delusion is that you consider zero temperature as the temperature that stops electrons, that's wrong view.
