The two figure panels show two ways to connect a real (non-ideal) voltmeter and a real ammeter in a circuit to calculate the resistance R. The internal resistance of the voltmeter is Rv and the internal resistance of the ammeter is Ra. The current flows from left to right in both panels, and the potential difference Vac between points a and c in both panels is the same. In panel (a)  the voltmeter reads Vac = 12.1 V and the ammeter reads I1 = 0.098 A. In panel (b) the voltmeter reads Vab = 12.0 V and the ammeter reads I2 = 0.100 A. I need help with Part E.
