Superconductors

There is a special type of conductor, called a superconductor that has no resistance, but the materials that make up superconductors only start superconducting at critical temperatures (very low temperatures approximately -170◦C).


Best conductors like silver, copper and gold do not show superconductivity.

Special properties:

• Allows the flow of electric current with minimal loss ofenergy
  

• Negates any applied external magnetic fields

Superconductors are used in transportation, electronic components, energy storage, power cables, etc.
