Having trouble with part B of this question

Jumper cables are connected from a fresh battery in one car to charge a dead battery in another car. The figure below shows the circuit diagram for this situation. While the cables are connected, the ignition switch of the car with the dead battery is closed and the starter is activated to start the engine. (Let R = 0.950 ? and Rs = 0.07 ?.)

Having trouble with part B of this question Jumper cables are connected from a fresh battery in one car to charge a dead battery in another car. The figure below shows the circuit diagram for this situation. While the cables are connected, the ignition switch of the car with the dead battery is closed and the starter is activated to start the engine. (Let R = 0.950 ? and Rs = 0.07 ?.) Determine the current in the starter Determine the current in the dead battery.

Explanation / Answer

applying kcl V/Rs + (V-12)/R + (V-12)/0.01=0

solving we get V=10.51

current through Rs=10.51/0.07 = 150.14A

current in the dead battery= (10.51-12)/0.95 = -1.568A
