10.1 Electromotive Force – University Physics Volume 2
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 12-V lamp attached to a 12-V battery, as shown in Figure 10.3.The battery can be modeled as a two-terminal device that keeps one terminal at a higher electric potential than the second terminal.
