Silver is the most electrically and thermally conductive metal. Other metals with a high level of electrical conductivity are copper and gold.Know More
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
Copper is a good conductor of electricity because the valence electrons are free and repel each other so strongly that it causes the repulsion of other electrons. This essentially forces the electricity down the piece of copper, or conducts it down the metal.Full Answer >
Some plastics can conduct electricity. Materials that insulate against electricity or do not conduct electricity are called dielectrics. While earlier plastics were dielectrics, scientists have developed plastics that can conduct electricity.Full Answer >
Gold is a very good conductor of electricity. It is often used as plating for connectors because it does not tarnish or corrode easily.Full Answer >
There is no metal that does not conduct electricity entirely, but there are some metals that are less effective conductors than others. Metal atoms have electrons in their outer shells that are not tied to any particular atom and can flow freely within the metal when electricity is applied.Full Answer >
