A galvanometer shows full scale deflection for a current Ig. If a shunt of resistance S1 is connected to the galvanometer, it gets converted into an ammeter of range (0 - I). When resistance of the shunt is made S2, its range becomes (0-2I). Then (S1/S2) is (A) (I + Ig)/ (I - Ig) (B) (I + Ig)/ (I - Ig) (C) (2I - Ig) / (i - Ig) (D) (I - Ig) / (2I - Ig)
