What is electricity? To begin to answer this question, we have to look at the composition of matter. All matter is made up of atoms, but it is far from simple to describe an individual atom. Atoms are of course far too small to be seen under the most powerful microscope, and we have to infer their construction from the way they behave and from the way they affect various forms of radiation beamed at them. Because nobody quite knows just what an atom really looks like, physicists construct models of atoms to help them explain and predict atomic behaviour.
