11.2.1 Questions and statements

What is absolute zero? What materials are the best superconductors? What is the reason of total losses in modern transformers? Practical application of superconductors is ..... Scientists from IBM found a ceramic material that became a superconductor at a temperature of 23 K. Landau and Ginzburg introduced a model which was useful in understanding electromagnetic properties of superconductors. A superconducting material cannot be returned to the normal state. The electrical resistivity of a mercury wire disappears when cooled below 4 K. Superconductors were once thought to be physically impossible.
