The coil of wire in a galvanometer has a resistance of RC = 67.7.The galvanometer exhibits a full-scale deflection when the currentthrough it is 0.276 mA. A resistor is connected in series with thiscombination so as to produce a voltmeter. The voltmeter is to havea full-scale deflection when it measures a potential difference of13.7 V. What is the resistance of this resistor?

Hey how would I solve this?

The coil of wire in a galvanometer has a resistanceofR_C = 52.0Î©. The galvanometer exhibitsafull-scale deflection when the current through it is 0.325 mA.Aresistor is connected in series with this combination so astoproduce a voltmeter. The voltmeter is to have afull-scaledeflection when it measures a potential difference of17.7 V. Whatis the resistance of this resistor?
