A substance that has no resistance to conducting an electric current.

Superconductor is a material that experiences a nearly total loss of electrical resistivity below a critical temperature
Helpful?           0
A material that becomes a perfect conductor of electricity when chilled to cold temperatures. Developments beginning in 1986 have raised the threshold temperature to levels which, in the near future, may provide wires capable of conducting large electric currents without line loss. Almost all substances have some resistance to electrical currents and this causes the loss of some of the electrical power generated. Only a superconducting wire could prevent such line losses because a current that is started in a superconductor can flow forever.

A material with zero resistance to the flow of electric current.

A superconductor is a material that conducts electricity with no wasted heat energy. Normal metals such as copper conduct electricity with up to 20% of the total energy wasted in the transmission of a current because of resistance heating of the wires.

(MRI) A material which loses its electrical resistance when cooled to an extremely low temperature. Superconductors are used in to manufacture electromagnets. Once the critical temperature is reached the electromagnet can operate with the use of very little electricity.

a perfect diamagnet, but there is more than this involved in the Meissner effect
Helpful?           0
a scientific oddity in which a substance, when cooled to extremely low temperatures, loses all electrical resistance (which theoretically allows an electrical charge to travel along it infinitely without degradation)
Helpful?           0
a special material that is a perfect conductor of electricity, usually at extremely low temperatures
Helpful?           0
a substance capable of allowing electrical current to pass through it without resistance
Helpful?           0
a substance that conducts electricity with no loss of current
Helpful?           0
a substance which allows an electrical current to flow without resistance, even when there is no continually applied potential
Helpful?           0
a substance which allows energy, or consciousness, to flow without resistance even in the absence of a continually applied potential
Helpful?           0
A substance, usually a metal alloy, whose electrical resistance abruptly drops to zero at low temperatures. MRI magnets commonly use titanium-niobium wires imbedded in a larger copper wire that is cooled with liquid helium to about 4 degrees absolute. The copper acts to conduct away heat in case a occurs and also acts as an insulator at superconducting temperatures. U-Z Unicorn A mythical creature that looks like a horse with a single horn on it's forehead.
Helpful?           0
A synthetic material that has very low or no electrical resistance. Such experimental materials are being investigated in laboratories to see if they can be created at near room temperatures. If such a superconductor can be found, electrical transmission lines with no little or no resistance may be built, thus conserving energy usually lost in transmission. Superconductors could also have uses in computer chips, solid state devices and electrical motors or generators.
Helpful?           0
A substance that holds a current with no noticeable resistance.
Helpful?           0
A superconductor is based on the conduction of high levels of electrical current through a specially made material that is kept at very low temperatures. The low temperature keeps the conductor's resistance low to allow for increased current passage.
Helpful?           0
An electric conductor that conducts an electric current without resistance at low temperatures.
Helpful?           0
Used in some electrical equipment. It is a material that when cooled to near absolute zero, has negligable electrical resistance.
Helpful?           0
A material or object through which electricity flows with zero resistance.
Helpful?           0
A material that conducts electricity with zero electrical resistance. In theory, the tiniest voltage will generate an infinite current in such a material, and a current will circulate around a superconducting loop forever.
Helpful?           0
Metal such as lead or niobium that, when cooled to within a few degrees of absolute zero, can conduct current with no resistance.
Helpful?           0
A material that becomes a perfect conductor of electricity because it offers no flow resistance and therefore results in no line losses. Superconducting materials are in the early stages of development.
