NettetR=VI g −GR=VI g −G. That is, the desired range of V volts in voltmeter will be shown by the galvanometer having a total of N divisions. N divisions of converted galvanometer = V volt. The least count of the converted galvanometer, L.C =V/N. Hence, we can convert the reading of galvanometer to volts using the relation. NettetApplying formula for conversion of galvanometer into voltmeter V = I g (G + S) To give maximum reading , full scale deflection current should pass through the galvanometer. V = (10 × 10 − 3) (90 + 910) = 10 V So, number of division n will be n = V Least count = 10 0.1 = 100 Hence, option (c) is the correct answer.
