Your car battery is wearing out in the cold, and delivers 11.4 V with an internal resistance of 0.01 ?. It's connected to a 2 ? load (your starter motor), and can't quite turn over the congealed mass of motor oil in your engine. Your friend pulls up with a healthy 12.6 V battery (also having internal resistance 0.01 ?) and connects jumper cables between the batteries.
Draw a diagram of this circuit.
Find the current in each part of this circuit.
Find the power delivered by the good battery, and discuss where this power goes, assuming that the emf's and resistances of each battery remain the same throughout the process.
