Why superconductors are not used often in everyday activities?

Because at present all superconductors must be super-cooled in a coolant such as liquid nitrogen to become superconductors.


How are superconductors different from conductors?

In superconductors, no electricity is wasted because there is no resistance to the flow of electrons. In conductors any electricity not used, is wasted.


Why are scientists trying to make superconductors that can work at warmer temperatures?

Because refrigerating superconductors to the cryogenic temperatures needed by current ones is expensive, severely limiting the applications they are used in.Metallic superconductors need cooling to the temperature of liquid helium.Copper oxide ceramic superconductors need cooling to the temperature of liquid nitrogen.Room temperature superconductors, if they exist, would need little or no cooling.


Do superconductors have a role in telecommunications?

Yes, they are used in telecommunications base stations.Some components needed in telecommunications base stations, most importantly filters, have better performance when superconductors are used instead of metals.


What contains bismuth?

Bismuth can be used in:- medicines- alloys- cosmetics- superconductors


What is a material that has no electrical resistance?

The class of materials called superconductors have no DC resistance when cooled below their transition temperature. This temperature varies with the material and is below 20K for metallic superconductors and generally below about 100K for oxide or "High Temperature" superconductors


Which has the lowest resistance semiconductors superconductors insulator conductor?

superconductors, they have no resistance.


What are most modern high temperature superconductors made of?

Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.


How Superconductivity arises in high temperature superconductors?

I think so the super conducting material used will melt


What are the uses of a superconductor?

Superconductors have zero resistance, and are used in powerful magnets for MRI etc, and magnetic levitation.


What is the definition of low temperature supercoductors?

In a way, all currently existing superconductors are "low-temperature", but some more so than others. The traditional superconductors work up to about 20 K (or minus 253 Centigrade); more recent "high-temperature superconductors" work up to 100 K or so. 100 K is still minus 173 Centigrade, but it is much "hotter" than the traditional superconductors. The new "high-temperature" superconductors apparently work different than the old-fashioned ones; at least, the theory that explains the traditional superconductors fails to explain how the new superconductors work.
