Web6. It produces no losses due to hysteresis. B. Dis-Advantages: 1. The moving coil instrument can only be used on D.C supply as the reversal of current produces reversal of torque on the coil. 2. It’s very delicate and sometimes uses ac circuit with a rectifier. 3. It’s costly as compared to moving coil iron instruments. 4. Webgalvanometer, instrument for measuring a small electrical current or a function of the current by deflection of a moving coil. The deflection is a mechanical rotation derived from forces resulting from the current.
