Two 1.50-V batteries—with their positive terminals in the same direction—are inserted in series into the barrel of a flashlight. One battery has an internal resistance of 0.390 Ω, the other an internal resistance of 0.120 Ω. When the switch is closed, a current of 600 mA occurs in the lamp. What fraction of the power dissipated is dissipated in the batteries?
