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
