When the lights of a car are switched on, an ammeter in series withthem read 10.0A and a voltmeter connected across them (parallel)reads 12.0V. When the electric starting motor is turned on, the ammeter reading drops to 8.00 A and the lights dim somewhat. Ifthe 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?
