Now let’s apply Kirchhoff’s rules to a simple battery circuit.
The circuit, shown in (Figure 1), is used to start a car that has a
weak (i.e., nearly discharged) battery (Figure 2). It includes two
batteries, each with an emf and an internal resistance, and two
resistors. Find the current in the circuit and the potential
difference Vab. In this example, if the emf of the 4 V battery is
increased to 16 V and the rest of the circuit remains the same,
what is the potential difference Vab?
