As an auto mechanic, you need to determine the emf and internal resistance of an old battery. You perform two measurements. In the first, you apply a voltmeter to the battery's terminals and read 11.8 V.11.8 V. In the second, an ammeter applied to the terminals indicates 19.5 A.19.5 A. What are the battery's emf and internal resistance?
