High accurate ammeter principle
Webammeter, instrument for measuring either direct (DC) or alternating (AC) electric current, in amperes. An ammeter can measure a wide range of current values because at high … WebCollegedunia Team. Difference between Ammeter and Voltmeter is that the Ammeter measures electric current whereas the voltmeter measures voltage. The ammeter comes in handy in order to measure the flow of current. While the voltmeter comes in handy for measuring the voltage and emf between the two points in the electric circuit.
