A small number of metals that lose nearly all their electrical resistance in certain temperature ranges with the result that very high currents can be transmitted with very low losses. Use of these materials for electric power generation (superconducting turbine generators), storage (superconducting magnetic energy storage system, SMES) and transmission (superconducting transmission cables) promises important technical and cost advantages.
materials that lose all resistance to the flow of current at low temperatures. They operate extremely fast and produce almost no heat.
Materials that don't have any resistance to electrical current flow. Zero resistance can be achieved only at very, VERY cold temperatures.
A class of metals and compounds whose resistances fall to virtually zero below a certain temperature, c, called the critical temperature.
These are materials in which the resistance drops to almost zero at a temperature near absolute zero. Super conductivity is exhibited by any of the metallic elements, their alloy and intermetallic compounds.
Go to Materials & Technology Superconductivity is a phenomenon occurring in certain materials at low temperatures that is characterized by the complete absence of electrical resistance and the damping of the interior magnetic field.
