Types of Conductors
Metals
Most conducting materials used for practical applications are metals. For example, the wire around your house probably uses copper wires as conducting materials or their alloys. The electric plugs have metal in them, and the internal mechanism of you electric irons also use metals as their conducting material. This is because metals have lots of free electrons and promote mobility. Some of the best metal conductors are Silver (Ag), Copper (Cu) and Gold (Au).
Non – Metals
There are some non – metals which are a very good conductor of electricity. For example, the carbon in the form of graphite is a very good conductor of electricity. If you see the structure of graphite, only three of the four carbon atoms are used for bonding. This leaves one electron free for bonding. However, most nonmetals are not good conductors of electricity.
Ionic Conductors
Conductors in their solution form are called ionic conductors. For example, saltwater is an ionic solution and is a good conductor of electricity.
Semiconductors
Although semiconductors are not as good at conducting electricity as conductors, they still have their uses. Examples of semiconductors are Germanium (Ge) and Silicon (Si).
