JEE MainPhysicsCurrent ElectricityNumerical+4 / −1
When a resistance of 5 Ω5 ~\Omega5 Ω is shunted with a moving coil galvanometer, it shows a full scale deflection for a current of 250 mA250 \mathrm{~mA}250 mA, however when 1050 Ω1050 ~\Omega1050 Ω resistance is connected with it in series, it gives full scale deflection for 25 volt. The resistance of galvanometer is ‾\underline{\hspace{2cm}}​Ω\OmegaΩ.
