B4 Two 1.50-V batteries-with their positive terminais in the same drection-are inserted in series into the barrel of a fiashilight. One battery has an internal resistance of G400 a, me other aninternal resistance of 0.180 2. when the switch is closed, a current of 600 mA occurs in the lamp.(a) What is the buit's resistance?(b) What traction of the chemical energy transformed eppears as internal energy in the batteries?

Solution: a). Since the batteries are connected in series, the net voltage of the batteries is the…

Two 150-V batteries-with their positiive terminals in the same drection-are inserted in series into the barel of a fashlight. One bartery has an internal vesistance of 0.400 , the oher an nternal resistance of 6.180 n when the switch is closed, a current of 600 mA occurs in the lamp (a) What is the bulb's resistance? (b) What fraction of the chemical energy transformed appears as internal energy in the batteries?
