Consider a galvanometer with an internal resistance of 60 O. If the galvanometer is being used as an ammeter (with no additional resistance) it deflects full scale when it carries a current of 0.5 mA. You want to use the same galvanometer as a voltmeter by connecting it through a series resistor to voltage source. A 1.0 V source produces full scale deflection of the meter. What is the value of the series resistor?
