Question

What is super conductor and types of conductor in chemistry?

Answer 1

Superconductors are materials that conduct electricity with no resistance. This means that, unlike the more familiar conductors such as copper or steel, a superconductor can carry a current indefinitely without losing any energy.

Answer 2

A superconductor is an element or metallic alloy which, when cooled below a certain threshold temperature, the material dramatically loses all electrical resistance. In principle, superconductors can allow electrical current to flow without any energy loss (although, in practice, an ideal superconductor is very hard to produce). This type of current is called a supercurrent.

The threshold temperature below which a material transitions into a superconductor state is designated as Tc, which stands for critical temperature. Not all materials turn into superconductors, and the materials that do each have their own value of Tc.

Types of Superconductors

Type I superconductors act as conductors at room temperature, but when cooled below Tc, the molecular motion within the material reduces enough that the flow of current can move unimpeded.Type 2 superconductors are not particularly good conductors at room temperature, the transition to a superconductor state is more gradual than Type 1 superconductors. The mechanism and physical basis for this change in state is not, at present, fully understood. Type 2 superconductors are typically metallic compounds and alloys.
