Q4\ B\ calculate the resistance value required to connected with a moving coil voltmeter to
produce one volt per division if the coil have 50 turns, with 4 cm long diameter and 3cm wide.
The flux density of the magnetic field in the air-gap is 0.1 Wb/m2.The control spring exerts a
torque of 2.4x104 N-m when the deflection is 100 divisions on the full scale. Neglect the
resistance of the voltmeter coil.
