Gold is a very good conductor of electricity. It is often used as plating for connectors because it does not tarnish or corrode easily. More »

Many metals, like silver, copper, gold and aluminum, are good thermal conductors. Thermal conductors are materials that heat passes through easily. Conduction, or the transfer of heat, can take place within a single mate... More »

Copper's outer electrons are detached easily, making it great at causing an electron chain reaction. Copper is also used because of its price. While its price is increasing, its still far cheaper than other conductors. More »

Graphite is a good conductor of electricity because its electrons are delocalized or free to move around. Graphite is structured into planes with tightly bound atoms. There is a great deal of distance between planes, and... More »

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 met... More »

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 cons... 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... More »
