Answer to Question #65779 in Electric Circuits for Helen

Question

When your car won’t start in really cold weather, it is often because your battery
has failed. A failing battery can sometimes be resuscitated by “jumping” it, as in the
circuit diagram below. Determine the current in the starter and in the failing battery.
With your solution, please re-draw the circuit diagram and label your loops and initial
current direction arrows.
