Consider the circuit below. It is something you might use to approximate the circuit being used while trying to jump start a car.
a) The elements in this drawing represent the dying battery and its internal resistance, the jumper battery and its internal resistance, and the starter motor. (Remember the jumper battery is used to charge the dead battery and power the starter motor.) Identify which parts represent each and explain your reasoning.
b) Find the current in the motor if JUST the bad battery is attached.
c) Find the current in the motor if JUST the good battery is attached.
d) Find the current in the batteries if they are attached to each other, but the motor is
removed.
e) Identify (label) the different currents in the circuit and write equations that could be
used to find currents. Then find the currents, How does each current compare to similar currents in parts b, c, and d?
