superconductivity
The property of a material whereby it has no resistance to the flow of an electric current

Currently, superconductivity can only be achieved at extremely low temperatures.

Superconductivity occurs in certain materials at very low temperatures. When superconductive, a material has an electrical resistance of exactly zero and no interior magnetic field (the Meissner effect). It was discovered by Heike Kamerlingh Onnes in 1911. Like ferromagnetism and atomic spectral lines, superconductivity is a quantum mechanical phenomenon. It cannot be understood simply as the idealization of "perfect conductivity" in classical physics
{i} quality of nearly perfect conductivity, ability of some materials to conduct electricity with virtually no resistance when chilled to temperatures near absolute zero (Physics)
About one third of all metals loose all electrical resistance at tempertures below a critical temperature Tc Many elemental metals are superconductors Some critical temperatures are: lead Tc = 7 2 K, tin Tc = 3 7 K, niobium Tc = 9 2 K, aluminum Tc = 1 2 K, mercury Tc = 4 2 K, and vanadium Tc = 5 3 K Compounds can have even higher critical temperatures YBa2Cu3O7 has a critical temperature of Tc = 92 K and HgBa2Ca2Cu3O8 has a critical temperature of Tc = 133 K Superconducting wires can carry currents with zero losses up to very high current densities Above a critical current density Jc, superconductivity is supressed A typical critical current density is 106 A/cm2 Superconductivity is also supressed by strong magnetic fields
[su pEr kan dEk tI vih ti]
A phenomenon occurring in many metals and alloys If these substances are cooled below a transition temperature, Tc, close to absolute zero, the electrical resistance becomes vanishingly small (see also Meissner effect and Josephson effect )
The pairing of ELECTRONs in certain materials when cooled below a critical temperature, causing the material to lose all resistance to electricity flow Superconductors can carry electric current without any energy losses
An electronic state of matter characterized by zero resistance, perfect diamagnetism, and long-range quantum mechanical order
Disappearance of electrical resistivity at low temperatures
the disappearance of electrical resistance at very low temperatures
Superconductivity is the ability of certain metals to allow electricity to pass through them without any resistance at very low temperatures. the ability of some substances to allow electricity to flow through them very easily, especially at very low temperatures. Almost total lack of electrical resistance in certain materials when they are cooled to a temperature near absolute zero. Superconducting materials allow low power dissipation, high-speed operation, and high sensitivity. They also have the ability to prevent external magnetic fields from penetrating their interiors and are perfect diamagnets (see diamagnetism). Since it was first discovered in mercury by Heike Kamerlingh Onnes in 1911, similar behaviour has been found in some 25 other chemical elements and in thousands of alloys and compounds. Superconductors have applications in medical imaging, magnetic energy-storage systems, motors, generators, transformers, computer components, and sensitive magnetic-field measuring devices
The loss in some materials of all electrical resistance at supercold temperatures
The ability of certain materials to carry an electric current with zero electrical resistance
