What is a superconductor?
Understand the Problem
The question is asking for a definition and understanding of what a superconductor is, including its properties and applications.
Answer
A superconductor conducts electricity with zero resistance below a critical temperature.
A superconductor is a material that can conduct electricity with zero electrical resistance and without energy loss, typically when cooled below a critical temperature.
Answer for screen readers
A superconductor is a material that can conduct electricity with zero electrical resistance and without energy loss, typically when cooled below a critical temperature.
More Information
Superconductors expel magnetic fields, a phenomenon known as the Meissner effect. They are essential in advanced technologies and applications such as MRI machines and Maglev trains.
Tips
Confusing zero resistance with low resistance. Superconductors must be at low temperatures to achieve their zero-resistance state.
