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 59.4 A and the potential difference across the battery terminals is 8.64 V. When only the car's lights are used, the current through the battery is 2.08 A and the terminal potential difference is 12.6 V. Find the battery's emf. Find the internal resistance.
