Silver is the best metal conductor, but graphene is the best overall material at conducting electricity. Graphene consists of carbon atoms arranged in extremely thin sheets, and has the lowest electrical resistance of an... More » Science Physics Electricity

In general, metals like copper and aluminum are the best conductors of electricity. Good conductors are able to allow electrons to easily flow through. More » Science Physics Electricity

Glass is not a good conductor of electricity and is classified as an insulator not a conductor. An electrical insulator is any material that does not allow electrons and electric charge to flow freely. These materials ma... More » Science Physics Electricity

According to NEWTON, ice can conduct electricity, but it's a very poor conductor. Water doesn't conduct electricity; impurities in the water (ions) do, and ions don't tunnel around very quickly in frozen water. More » Science Physics Electricity

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 » Science Physics Electricity

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 » Science Physics Electricity

Although many people think water conducts electricity well, pure water is a poor conductor since its molecules do not have free electrons to travel and thus transfer current. Pure water, however, rarely exists in nature.... More » Science Physics Electricity
