Civilization advance.
When an electric
current passes through any
material, some part of that current is lost to
resistance. A material with little resistance to the flow of
electricity is called a
conductor, and these materials are useful for building electric devices. Many conductors, when cooled to temperatures near
absolute zero, lose all resistance to current. A material with no resistance to the flow of electricity is a superconductor. Recent developments hint that some unusual materials may be superconductive even at room temperatures.
