When a galvanometer is shunted with a $4$ Ω resistance, the deflection is reduced to one-fifth. If the galvanometer is further shunted with a $2$ Ω wire, determine current in galvanometer now if initially current in galvanometer is $I_{0}$ . (Given: Main current remains same)

When a galvanometer is shunted with a $4 Ω$ resistance, the deflection is reduced to one-fifth. If the galvanometer is further shunted with is further shunted with a $2 Ω$ wire $(2 Ω a n d 4 Ω$ resistors are connected in parallel), the further reduction in the deflection will be(the main current remains the same).
