Phsics Problem,Please show steps. A) You are given a battery, which has, of course, a particular emf and a particular internal resistance (Rint). You decide to determine its internal resistance and its emf by connecting an ammeter in series with a variable resistor across the battery. By varying the resistance you can draw more or less current from the battery. You also use a voltmeter to measure the voltage across the terminals of the battery. Case 1) When you draw...
