Electromotive Force

If the electromotive force is not a force at all, then what is the emf and what is a source of emf? To answer these questions, consider a simple circuit of a lamp attached to a battery, as shown in Figure 6.1.2.The battery can be modeled as a two-terminal device that keeps one terminal at a higher electric potential than the second terminal.
