To extend the useful range of a voltmeter, an additional resistor, Rseries, is placed in series with the voltmeter as shown in the figure. If the internal resistance of the voltmeter is Ri,V, determine the resistance that the added series resistor has to have to extend the useful range of the voltmeter by a factor N. Then, calculate the resistance the series resistor must have to allow a voltmeter with an internal resistance of 1.00 MΩ and a maximum range of 1.00 V to measure potential differences up to 100. V. What fraction of the total 100.-V potential drop occurs across the voltmeter, and what fraction of that drop occurs across the added series resistor
