This is an electrifying subject if ever there was one. I think the historical angle of it alone could fill a book. Electric was probably the only one of the three existing before the time of Faraday. Then the need for distinction between static and "flowing" electricity arose, with the increasing use of the latter in electrical appliances. Electricity was supposed to flow only in "conductors" at that time. In "vacuum tubes", lo and behold, electrons traversed emptiness: reason enough to create a new word, together with the attendant profession, electronics.
