The Loss of Electrical Resistance

1 The Loss of Electrical Resistance. As mentioned previously, a superconductor displays an abrupt change in resistivity when it is cooled below the critical temperature. 

However, in the case of a superconductor, below the critical temperature the resistivity abruptly becomes zero. This means that a current can flow indefinitely through the material.

Among the more important changing properties are the loss of electrical resistance and the appearance of the perfect diamagnetism. The thermal conductivity in the superconducting state differs from that in the normal state. A...
