Q:

What materials conduct electricity?

A:

Quick Answer

The most common materials that are good conductors of electricity are metals, but other materials, such as carbon, can also conduct electricity in certain forms. When carbon atoms are arranged in a certain structure like graphene, they can conduct electricity well, but are poor conductors in materials like diamond.

Full Answer

Metals are known as the best conductors due to their natural state. Metals are typically found with one or two valence electrons in their outer shells, which allow other electrons (from electricity) to transfer efficiently through the material. The best metal conductors are silver, copper and gold while the worst are titanium and mercury.

    Does oil conduct electricity?

    A:

    Oils conduct electricity minimally under normal conditions, which makes them useful as insulators. The extent of electrical conductivity depends on the concentration of impurities. The presence of salts and other substances generally increases the electrical conductivity of oil.

    Does titanium conduct electricity?

    A:

    Titanium is able to conduct electricity and heat, but it does so poorly. It is also very resistant to corrosion, and to damage from many acids, so it is a good choice of metal in hostile environments where heat, electricity and corrosion could be potentially damaging.

    Does brass conduct electricity?

    A:

    Brass does conduct electricity, but it is not a very good conductor. Not all metals conduct electricity to the same extent. Brass has a low electrical conductivity of only 28 percent, compared to metals such as silver and copper that have almost perfect electrical conductivity.
