Two 1.50V batteries -- with their positive terminals in the same direction-- are inserted in series into the barrel of a flashlight. Onebattery has an internal resistance of 0.220 , the other aninternal resistance of 0.170 . When the switch isclosed, a current of 600 mA occurs in the lamp.

(a) What is the lamp's resistance?

(b) What fraction of the chemical energy transformed appears asinternal energy in the batteries?
