CONDUCTORS

==Conductors== Conductors are substances with free charges (generally electrons) that can move / flow through them. For example, all metals are conductors and allow electrons to pass through them easily. Carbon can also be a conductor e.g. a pencil lead (graphite) contains carbon and conducts electricity. Metal wires are usually used in circuits. [image:http://i.imgur.com/fgUOwpx.gif]
