What is Superconductivity?Superconductivity DefinitionSuperconductivity is defined as the property of certain materials to have zero electrical resistance at very low temperatures.Critical TemperatureThe critical temperature is the specific temperature below which a material becomes superconducting.Properties of Superconductors Zero electric resistance (infinite conductivity) Meissner Effect: Expulsion of magnetic field Critical Temperature/transition temperature Critical Magnetic field Persiste
