A moving coil galvanometer has 50 turns and each turn has an area 2 × 10−4 m2. The magnetic field produced by the magnet inside the galvanometer is 0.02 T. The torsional constant of the suspension wire is 10−4 N m 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 50Ω . 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 __________.

    Calculating the Shunt Resistance Value:

    1. Determine the Current Range:
    - Full scale deflection occurs at 0.2 rad with a resistance of 50 .
    - Using Ohm's Law, the current at full scale deflection is I = V/R = 0.2/50 = 0.004 A.
    - To measure current up to 1.0 A, a shunt is needed to divert 1 - 0.004 = 0.996 A.

    2. Calculate the Resistance of the Shunt:
    - The shunt resistance (Rs) can be calculated using the formula: Rs = R * (Ig/I - 1), where Ig is the full-scale current.
    - Plugging in the values, Rs = 50 * (0.004/0.996 - 1) = 5.56 .
    Therefore, the value of the shunt resistance that needs to be added in parallel to the galvanometer is 5.56 .
