Superconductors are materials that can conduct electricity without resistance from "summary" of The World of Physics 2nd Edition by John Avison
Superconductors are materials that can conduct electricity without resistance. This means that when an electric current is passed through a superconductor, there is no loss of energy due to resistance, unlike in ordinary conductors. The absence of resistance allows superconductors to carry large currents without any energy loss, making them highly efficient for a variety of applications. The phenomenon of superconductivity was first discovered in 1911 by Dutch physicist Heike Kamerlingh Onnes, who found that the resistance of mercury dropped to zero when cooled to very low temperatures. Since then, scientists have discovered many other materials that exhibit superconducting properties at even higher temperatures. One of the key characteristics of superconductors is their critical temperature, above which they lose their superconducting abilities. This critical temperature varies depending on the material, with some superconductors requiring extremely low temperatures close to absolute zero, while others can superconduct at higher tempe...
