When the lights of an automobile are switched on, an ammeter in series with them reads 12 A and a voltmeter connected across them reads 15 V. See Fig. 28-52. When the electric starting motor is turned on, the ammeter reading drops to 8.0 A and the lights dim somewhat. If the internal resistance of the battery is .0500 Ohms and that ofthe ammeter is negligible what are the
a) emf of the battery and
b) the current through the starting motor when the lights areon? Thank you so much for your help.
