An old car battery that has an emf of e m f1 = 11.5 V and an internal resistance of 55.0 mΩ is connected to an R = 2.00 Ω resistor. In an attempt to recharge the battery, you connect a second battery that has an emf of e m f2 = 12.6 V and an internal resistance of 10.0 mΩ in parallel with the first battery and the resistor with a pair of jumper cables.

(a) Draw a diagram of the circuit.

(b) Find the current in each branch of the circuit. (Enter your answers from smallest to largest.)

(c) Find the power supplied by the second battery. Assume that the emfs and internal resistances of both batteries remain constant.

Discuss where that power is delivered. Assume that the emfs and internal resistances of both batteries remain constant.
