Somewhere it is written that superconductors have negative coefficint of resisitivity so, at absolute temperature it behaves like an insulator. But according to the concept of superconductivity below the critical temperature, superconductors have zero resistivity or in other words high conductivity. How can both these statemnts can be true?
