Critical Temperature

Critical temperature is the highest temperature at which a material can become superconducting—meaning it can conduct electricity with zero resistance. Above this temperature, the material behaves like a normal conductor, with some electrical resistance. When cooled below the critical temperature, the material transitions into a superconducting state, allowing electricity to flow perfectly without energy loss. This property is important for applications like powerful electromagnets and efficient power transmission. The exact critical temperature varies between materials and is a key factor in developing practical superconductors.
