A moving coil galvanometer has 50 turns and each turn has an area 2 × 10 –4 m 2 . The magnetic field produced by the magnet inside the galvanometer is 0.02T. The torsional constant of the suspension wire is 10 –4 Nm rad –1 . When a current flows through the galvanometer, a full scale deflection occurs if the coil rotates by 0.2 rad. The resistance of the coil of the galvanometer is 50 Ω Ω . This galvanometer is to be converted into an ammeter capable of measuring current in the range 0 – 1.0A. For this purpose, a shunt resistance is to be added in parallel to the galvanometer. The value of this shunt resistance, in ohms, is __________.
