A sick car battery with an emf of 11.4 V and an internal resistance of 0.01 Ω is connected to a load of 2.0 Ω. To help the ailing battery, a second battery with an emf of 12.6 V and an internal resistance of 0.01 Ω is connected by jumper cables to the terminals of the first battery.

(a) Draw a diagram of this circuit.

(b) Find the current in each part of the circuit.

(c) Find the power delivered by the second battery and discuss where this power goes, assuming that the emf and internal resistances of both batteries remain constant.
