Three friends decided to connect their individual car batteries in parallel using ideal cables (negligible resistance) to power up the car of their fourth stranded friend as shown in this circuit. Unknown to them, their batteries are not fully charged and have different series resistance values and voltages as indicated. The starter motor of the fourth friend's car has an effective resistance of 0.185 ohms. 0.025 gho 0.020 ohm 12 V +11.2V 0.030 obro 0.050 ohm + 11.8 V +10.0 V MRm = 0.18502
