As explained in earlier editions of this series, electricity occurs as a result of electrons flowing in a particular direction. Electrons can however not travel through all mediums. Some media or materials permit the movement of electrons and so they are called Conductors, while some materials do not allow the free movement of electrons and so they are called Insulators. Examples of conductors are basically all metals and human beings, while examples of insulators are dry wood, bricks, ceramics, glasses, plastics and so on.
