When a car's starter is in use, it draws a large current. The car's lights draw much less current. As a certain car is starting, the current through the battery is 55.8 A and the potential difference across the battery terminals is 8.28 V. When only the car's lights are used, the current through the battery is 1.82 A and the terminal potential difference is 12.9 V.

Find the battery's emf.


Find the internal resistance.

    A real battery is not just an emf. We can model a real 1.5 V battery as a 1.5 V emf in series with a resistor known as the "internal resistance", as shown in the figure(Figure 1) . A typical battery has 1.0 Ω internal resistance due to imperfections that limit current through the battery. When there's no current through the battery, and thus no voltage drop across the internal resistance, the potential difference between its terminals is 1.5 V,...
