superconductivity

[ soo-per-kon-duh k-tiv-i-tee ]
/ ˌsu pərˌkɒn dəkˈtɪv ɪ ti /

noun Physics.

the phenomenon of almost perfect conductivity shown by certain substances at temperatures approaching absolute zero. The recent discovery of materials that are superconductive at temperatures hundreds of degrees above absolute zero raises the possibility of revolutionary developments in the production and transmission of electrical energy.

Scientific definitions for superconductor

superconductivity
[ sōō′pər-kŏn′dŭk-tĭvĭ-tē ]

The ability of certain metals or alloys to conduct an electric current with almost no resistance. Superconductivity usually occurs close to absolute zero, at temperatures approaching -459.67°F (-273.15°C), but has also been observed at temperatures as high as -200°F (-128.88°C).

Cultural definitions for superconductor (1 of 3)

superconductor

A material that can develop superconductivity (see also superconductivity).

notes for superconductor

Superconductors are used to make large electromagnets, and they are starting to play a major role in industry.

Cultural definitions for superconductor (2 of 3)

superconductivity
[ (sooh-puhr-kon-duk-tiv-uh-tee) ]

A property of some materials in which their electrical resistance drops to zero, and they acquire the ability to carry electric current (see also current) with no loss of energy whatsoever. Formerly, materials developed superconductivity only at temperatures near absolute zero, but new materials have been found that remain superconductive at temperatures above those of liquid nitrogen. The goal of current research is to find a material that remains superconductive at room temperature.

superconductivity
[ (sooh-puhr-kon-duk-tiv-uh-tee) ]

A property of materials by which their electrical resistance goes to zero, and they acquire the ability to carry electric current (see also current) with no losses whatsoever.

notes for superconductivity

Formerly, materials showed superconductivity only near absolute zero, but new materials have been found that are superconducting at much higher temperatures.
