Question

What is conductance and superconductors

Answer 1

It is told that a conductor which has zero resistivity is called perfect conductor and resistivity varies along with temperature directly. by lowering the temperature of a conductor, it is possible to have zero resistivity state for a conductor and to have super conductivity state. Does it mean that perfect conductors are superconductors and vice-verse? Or I have lack of sufficient understanding in the regards to this subject? I will be more than happy for clear responses.

Answer 2

Answer:

Superconductivity is a set of physical properties observed in certain materials where electrical resistance vanishes and magnetic flux fields are expelled from the material. Any material exhibiting these properties is a superconductor.
