Two 1.65 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 R₁ = 0.265 , the other an internal resistance of R₂ = 0.154 . When the switch is closed, a current of 0.600 A passes through the lamp. (a) What is the lamp's resistance? 22 (b) What fraction of the power dissipated is dissipated in the batteries? %
