Homework Statement


Two parts:

With the jumper cables attached, how much current passes through the starter motor?

With the jumper cables attached, how much current passes through the dead battery?


Homework Equations


Ohm's Law and Kirchhoff's Laws


The Attempt at a Solution


Well I've already figured out that the good battery can supply the starter motor with a 200A current and the dead battery can provide it with a 14.5A current. I found both of these answers using Kirchhoff's Loop Law. I'm honestly lost from here though.
