(a) Find the resistance that must be placed in series with a 10.0 galvanometer having a 125 µA sensitivity to allow it to be used as a voltmeter with a 500 V full-scale reading. (Answer to the nearest ohm.)
(b) Find the resistance that must be placed in series to allow it to be used as a voltmeter with a 0.300 V full-scale reading. (Answer to the nearest ohm.)
