Chapter 20, Problem 20.32(choose chapter or problem)
In a car, the headlights are connected to the battery and would discharge the battery if it were not for the alternator, which is run by the engine. Figure 20.29 indicates how the car battery, headlights, and alternator are connected. The circuit includes an internal resistance of 0.0100 for the car battery and its leads and a resistance of 1.20 for the headlights. For the sake of simplicity, the alternator is approximated as an additional 14.00-V battery with an internal resistance of 0.100 . Determine the currents through the car battery (IB), the headlights (I H), and the alternator (IA).
