... across a voltage difference V , where the work W = qV . For example, a 3 Coulomb charge that moves across 1.5 Volts, has had 4.5 Joules of work done on it by the field. The voltage difference is roughly equal to the electric field multiplied by the distance moved, so V ≈ Ed. A battery is capable of ...

History of electromagnetic theory
For a chronological guide to this subject, see Timeline of electromagnetic theory.The history of electromagnetic theory begins with ancient measures to deal with atmospheric electricity, in particular lightning. People then had little understanding of electricity, and were unable to scientifically explain the phenomena. In the 19th century there was a unification of the history of electric theory with the history of magnetic theory. It became clear that electricity should be treated jointly with magnetism, because wherever electricity is in motion, magnetism is also present. Magnetism was not fully explained until the idea of magnetic induction was developed. Electricity was not fully explained until the idea of electric charge was developed.
