Figure 22.2: Kirchhoff plots of two simple electric circuits.Left:A simple circuit with one loop. The resistor
ris meant to model the battery internal resistance;Eis the battery electromotive force; andVDEIris
the terminal voltage.Right:A more complex circuit. Notice how each battery causes a rise in potential, and
each resistor causes a drop in potential. (From Ref. [17].)
