Question

What do you understand by superconductivity?

Answer 1

1. Superconductivity is a phenomenon in which a material shows absolutely zero electrical resistance when cooled below a certain critical temperature known as the superconducting transition temperature.
2. In this state, the material allows electric current to flow indefinitely without any loss of energy.
3. Superconductors also exhibit another unique property called the Meissner effect, where they expel magnetic fields completely from their interior, becoming perfectly diamagnetic.
