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.
periodic table allows you to determine weather or not the elements will conduct electrocoty
superconductors, they have no resistance.
Because at present all superconductors must be super-cooled in a coolant such as liquid nitrogen to become superconductors.
Resistance decreases with the decrease of temperature. Superconductors are made by lowering the temperature.
Superconductors have the potential to drastically increase computer performance. They can increase the data transfer rates while reducing heat output.
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.
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.
In superconductors, no electricity is wasted because there is no resistance to the flow of electrons. In conductors any electricity not used, is wasted.

Superconductors are materials that let current or electricity pass through them. Insulators are materials that don't allow current or electricity to pass through them. Superconductors are mostly all metals. Insulators are wood, plastic, and paper.
