Rectifier Type Ammeter. There are many types of AC ammeters one of the most coman has a a full wave rectifier in its input circuit and the out put of this rectifier is applied to a deflected coil of the meter The current flowing in the coil will react with magnetic field of the meter mechanism and the pointer attached to the coil will be deflected.
PDF fileresistor in series with the coil AC ammeters and voltmeters can be constructed by using rectifier circuits with PMMC instrument Ohmmeters can be made from precision resistor PMMC instruments and batteries Multirange meters are also available which combine ammeter voltmeter and ohmmeter functions all in one instrument.
Rectifier – Explanation, Working, Types, Applications
The rectifier ammeter uses the moving coil along with the rectifier for measuring the current The main use of the rectifier is to convert the alternating current into the direct current The rectifier ammeter consists the four rectifier elements which arrange in the form of the bridge along with the moving coil ammeter.
