Today, because it is such a good conductor of electricity, copper is mostly used in electrical generators and motors, for electrical wiring, and in electronic goods, such as radio and TV sets. Copper also conducts heat well, so it is used in motor vehicle radiators, air-conditioners and home heating systems.
