How is a galvanometer converted to an ammeter
WebN 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 V G = n x L.C V G = Potential difference in volts n = No. of divisions in galvanometer L.C = Least count of the converted voltmeter WebThe ammeter reads 3 A. The same galvanometer is converted into a voltmeter by connecting a resistance of 1 0 1 Ω in series. This voltmeter is connected as shown in figure (i i). Its reading is found to be 4 / 5 of the full scale reading. If the full scale deflection current of the galvanometer is 1 0 0 x A. Find x.
