The electrical resistivity of gold is 0.022 micro-ohm m at 20 °C. The thermal conductivity is 310 W m-1 K-1at the same temperature. The corrosion resistance of gold is perhaps one it’s most useful properties. Electrode potentials are a useful method for representing the tendency of a metal to corrode.

Gold is a very good conductor of electricity. It is often used as plating for connectors because it does not tarnish or corrode easily. Even though copper and silver are better conductors than gold, gold retains its conductivity longest because it does not tarnish or corrode easily.

Although it is the best conductor, copper and gold are used more often in electrical applications because copper is less expensive and gold has a much higher corrosion resistance. Because silver tarnishes, it is less desirable for high frequencies because the exterior surface becomes less conductive.

When an electric body was placed on this plate, a portion of the electricity will pass through the gold leaves charging them to repel each other.  This is the measure of the charge. This is a very sensitive instrument used to detect small quantities of the electricity.

Gold is highly conductive to electricity, and has been used for electrical wiring in some high-energy applications (only silver and copper are more conductive per volume, but gold has the advantage of corrosion resistance).

Gold conducts electricity, does not tarnish, is very easy to work, can be drawn into wire, can be hammered into thin sheets, alloys with many other metals, can be melted and cast into highly detailed shapes, has a wonderful color and a brilliant luster. Gold is a memorable metal that occupies a special place in the human mind.
