Q.48. A moving coil of a galvanometer when shunted with 2Ω2\Omega resistance gives a full scale deflection for a current of 500 mA. When a resistance of 470Ω470\Omega is connected in series it gives a full scale deflection for 10V potential applied on it. The value of resistance of galvanometer coil is _______ Ω\Omega.
