Measurements made on circuits that contain large resistances can be confusing. Consider a circuit powered by a 15 V battery (of negligible internal resistance) with a 10 MN resistor in series with an unknown resistor, R. As shown in Figure 7, a particular voltmeter reads V = 0.366 V when connected across the 10 MN resistor and V = 7.317 V when connected across the unknown resistor. Determine the value of R. SS AV=0.366V AV=7.317V ww ww 10MN ww 10MN AV=15V V=15V Figure 7: A voltmeter affecting a circuit.
