Substances, which allow electric current to flow through them, are called conductors. Those, which do not, are called insulators. Metals behave as conductors because of their structure. In a metal structure the metal atoms release their outermost electrons to form an “electron cloud” throughout the whole structure.

Some conductors are better than others. Copper is a conductor than iron. When the electrons are moving through the metal structure they bump into the metal ions and this causes resistance to the electron flow or current. In different conductors the ease of flow of
