The world relies on conductors made primarily of copper and aluminum for transmitting and carrying electrical power, fabricating motors and generators, and myriad other applications. Such conductors, because they have nonzero (small but not exactly zero) electrical resistance, dissipate or lose a small portion of the power they transport.
