A galvanometer with full-scale deflection of 10 mA is to be converted to a voltmeter with full-scale deflection of 5v. the resistance of the galvanometer is

Answer Details

R = (Vg)/lg = G, where lg = current through galvanometer
R = resistance of the multiplier
G = resistance of the galvanometer
∴ G = (vg-R)/lg 5(1000/10) - 490 = 500 -490 = 10Ω
