Conductivity is measured by an element's ability to transmit energy. If an element is considered to be electrically conductive, it means that it has the ability to conduct electricity. Thermal conductivity refers to the transfer of heat. Most metals are able to conduct electricity.
Although silver is the most electrically conductive element, copper and gold are more commonly used in wiring and electronics. Copper is used because it is less expensive. Gold is used because it does not corrode as easily as other metals. Nickel, iron, platinum, zinc and aluminum also have high electrical conductivity. Alloys like bronze and brass are also electrically conductive.Learn more about Electricity
