When cooled this contains almost zero resistance?
Anything with the property of zero electrical resistance is called a super-conductor.
A material that has almost zero resistance when it is cooled to low temperatures is a....?
Super Conductor :)
What is the difference between superconductors and normal conductors?
Normal conductors have resistance which restricts the flow of electricity and wastes some of the energy as heat. The resistance increases with the length of the conductor. Superconductors have close to zero or zero resistance and a few other properties, but the resistance is the most important one because it means electricity can flow more efficiently through it. The drawback is that all the superconductors we know of today have to be cooled down to EXTREMELY low temperatures to achieve superconductivity.
Is A superconductor is A conductor having zero resistance?
Yes, a superconductor has zero resistance.
Why copper strips are used in meter bridge wire?
The resistivity of copper is very low and as the strip is so thick then resistance would be almost zero.

Anything with the property of zero electrical resistance is called a super-conductor.
What is time constant of capacitor when resistance is zero?
Time constant in an RC filter is resistance times capacitance. With ideal components, if the resistance is zero, then the time constant is zero, not mattter what the capacitance is. In a practical circuit, there is always some resistance in the conductors and in the capacitor so, if the resistance is (close to) zero, the time constant will be (close to) zero.
What is fault resistance?
Not all 'short circuits' are 'dead-shorts' -i.e. the resistance between the two conductors (or a conductor and earth) is not necessarily zero ohms -especially when the insulation between them has not completely broken down. The actual resistance is called the 'fault resistance'.

Are copper and silver super conductors?
No. A conductor is a good carrier of electricity or heat. A superconductor is a material in which the resistance to electrical flow is zero. Silver and copper are fairly good conductors, but some energy is lost.

Do the super conductors have real zero electrical resistance or is it a virtual one?
A superconductor truly has zero electrical resistance.It took scientists a half century to explain why, so this answer will omit the explanation of the effect.
What is almost zero gravity called?
microgravity
Is cobalt a super conductor of electricity?
conductorCobalt is a metal. Metals are good conductors of heat and electricity.
Is A superconductor is A conductor having zero resistance?
Yes, a superconductor has zero resistance.
What are conductors and insulators of electricity?
Conductors are materials that pass electrical current easily, that is, with low resistance. Insulators are materials that do not pass electrical current easily, that is, they have high resistance. Conductors are ordinarily metals, and insulators are ordinarily nonmetals. Some examples of conductors are: Silver, Copper, Carbon, and Aluminum. Some examples of insulators are Glass, Nylon, and Wood (as well as Air and Vacuum). Conductivity is a function of the mobility of Electrons in the materials in question. Conductors have high mobility and conductors have low mobility. Semiconductors are materials that have some properties of both conductors and insulators. Germanium and Silicon are well known semiconductors. Superconductors are materials that pass electrical current with zero resistance. All known superconductors perform this function only at very low temperatures, far below those encountered in Earth environments (i.e. from around 77 degrees above absolute zero down, or, in other words, below about -320 degrees F).
What are the property of superconductor?
Super conductors are conducting materials which below a specific temperature offer zero resistance to the conduction of current : Currently, superconductivity can only be achieved at extremely low temperatures.
