Question: Two automobile batteries are connected in parallel to power a wheelchair. If each of the batteries has electromotive force 12V and internal resistance r=0.045 Ohms, and the wheelchair motor has resistance R=1.5Ohms,
Part A: Find the current provided to the motor.
Part B: What would be the current delivered to the motor if the batteries were connected in series?
I need help to determine the current provided to the motor.
