In Figure 1, are we measuring the current passing through the resistor R only? If not, what are we measuring? If the resistance of the voltmeter Ry is about 100 times R, what is the percent error when we calculate the resistance R' = V/I using the current measured by the ammeter in Figure 1? If you have difficulty in solving the above problem you can use some arbitrary numbers, say, R = 5.0 2, Rv = 100 R = 500 2 and V = 20.0 V. Find I, calculate R' and the percent error.
