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.

    Is iron a good conductor?

    A:

    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.

    Why is graphite a good conductor of electricity?

    A:

    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 they are bonded weakly together, allowing the electrons to move around.

    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.
