The coil of wire in a galvanometer has a resistance of RC = 75.0 Ω. The galvanometer exhibits a full-scale deflection when the current through it is 0.200 mA. A resistor is connected in series with this combination so as to produce a voltmeter. The voltmeter is to have a full-scale deflection when it measures a potential difference of 14.0 V. What is the resistance of this resistor?
