WebFor a voltmeter with ranges of 1 volt, 10 volts, 100 volts, and 1000 volts, the multiplier resistances would be as follows: The advantage, of course, is that the individual multiplier resistor values are more common (900k, 90k, 9k) than some of the odd values in the first design (999.5k, 99.5k, 9.5k). WebPurpose: To measure the internal resistance of practical voltmeters, and to examine the effect of a voltmeter’s internal resistance on the operation of a circuit it is monitoring. Theory: A practical voltmeter is modeled using a resistance, RM in parallel with an ideal voltmeter, as shown in the equivalent circuit below. Figure 1.
