There is really no complete theory of superconduction yet. It is believed that in certain materials - the "classical" superconductors - the current is transported by Cooper pairs (i.e., pairs of electrons). However, the classical theory doesn't really explain superconduction in the more recently discovered high-temperature superconductors.
What else can I help you with?
What material that displays near zero resistance at a low temperature is called a(n)?
superconductor.
A material that has almost zero resistance when it is cooled to low temperatures is a....?
Super Conductor :)
Is A superconductor is A conductor having zero resistance?
Yes, a superconductor is a material that can conduct electricity without any resistance at very low temperatures. This means that once a current is applied, it can flow indefinitely without any loss of energy due to resistance.
Does a superconductor expel a magnetic field?
As a superconducting material transitions into its superconducting state, it ejects internal magnetic fields. In that light, yes, a superconductor could be said to expel a magnetic field according to what is called the Meissner effect. A link can be found below.
A superconductor performs best at?
A superconductor performs best at extremely low temperatures close to absolute zero, around -273 degrees Celsius. At this temperature, the material exhibits zero electrical resistance and can conduct electricity with maximum efficiency without any energy loss.
A material that has no electrical resistance?
That's a "superconductor".
What material that displays near zero resistance at a low temperature is called a(n)?
superconductor.
A material that has almost zero resistance when it is cooled to low temperatures is a....?

Is mercury the planet an example of superconductor?
Pure mercury will exhibit superconductivity at 4.2 degrees Kelvin. It was the first superconductive material that H. Kamerlingh Onnes found in 1911.
What flows indefinitely in a superconductor?
A current of electricity can flow at the same strength for an indefinitely long time in a superconductor but only for as long as the superconductor is held below its critical temperature. If its temperature were allowed to rise to its critical temperature - or higher - the material would no longer behave as a superconductor: it would acquire resistivity which would restrict the flow of current.
Is A superconductor is A conductor having zero resistance?
Yes, a superconductor is a material that can conduct electricity without any resistance at very low temperatures. This means that once a current is applied, it can flow indefinitely without any loss of energy due to resistance.
A material showing perfect conductivity and Meissner effect below a critical temperature Is this true or false?
Superconductor

What is the only insulator from magnetism?
A superconductor is the only material that completely repels magnetic fields, acting as an insulator from magnetism. This phenomenon is known as the Meissner effect, where a superconductor expels magnetic fields from its interior when it transitions to a superconducting state.
What makes a super conductor?
A superconductor is a material that can conduct electricity without any resistance when cooled below a certain critical temperature. This results in zero electrical resistance and allows a current to flow without losing energy to heat.
Is salt water a superconductor?
No. Salt water is a conductor but not a superconductor.
