Silver is the most electrically and thermally conductive metal. Other metals with a high level of electrical conductivity are copper and gold.Continue Reading
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
Iron is a good conductor of electricity but not the best. Iron is a metal, which makes it a much better conductor than an insulator, but different metals have different conductivity levels. Iron is a relatively cheap metal and is widely used in products requiring conductance.Full Answer >
Silicon is typically a very poor conductor of electricity and often considered an insulator. However, a process called doping introduces a small amount of other material into the crystal structure to convert silicon from an insulator to a semiconductor. Semiconductors are essential parts of computers and other electronics.Full Answer >
Citric acid is not a good conductor of electricity. This is because it is an example of a weak acid, which breaks down in water quickly.Full Answer >
Saltwater is a good conductor of electricity because it is an electrolyte solution. Substances such as salts, acids and hydroxides that also are electrolytes can conduct electric current. Saltwater is a mixture that consists of water and sodium chloride. When sodium chloride dissolves in water, the water separates the sodium and chlorine ions.Full Answer >
