Car A has a dead battery and car B gives a jump to it. I connect the positive of battery B to the positive of battery A and the negative of battery B to the body of car A.
1. Am I essentially creating a separate circuit by choosing a different ground than that of battery A? How is the current flowing back to battery B?
2. How many such separate circuits are theoretically possible ? For example, let's say , battery B is not strong enough, so I leave the connections as they are and bring battery C. I connect the positive of battery C to that of battery A (and of B). Where could I connect the negative of battery C for this arrangement to work?
Thanks
