Q:

What is the best conductor of electricity?

A:

Quick Answer

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 any commonly known material.

Full Answer

Most of the best conductors of electricity are metals. The best conductors are silver, gold and copper, while the worst are mercury and certain alloys of stainless steel. As a general rule, elements with a single valence electron are better conductors than those with more. They are able to displace electrons easier to allow the passage of electrons from electricity through the material.

    Why is water a poor conductor of electricity?

    A:

    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. Salts, sediments and minerals often mix with water and create ions that conduct electricity.

    Is plastic a conductor of electricity?

    A:

    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.

    Is glass a conductor of electricity?

    A:

    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 make it hard for electric current to flow.
