Non-uniform Scale of Electrodynamometer Type Instrument
Unlike a PMMC instrument, the electrodynamometer type instrument has non-uniform scale. The non-uniform scale of this instrument can be explained by the equation of deflection. As we know that the deflection in electrodynamometer type ammeter and voltmeter is given as Ɵ = KI2dM/dƟ for ammeter and Ɵ = KV2dM/dƟ for voltmeter Therefore, if dM/dƟ is … Read more
