Ammeter | Definition, Types, Symbol, & Facts | Britannica
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 values only a small portion of the current is directed through the meter mechanism; a shunt in parallel with the meter carries.
How to Use an Ammeter: 10 Steps (with Pictures) - wikiHow
WebDec 9, 2023 · Current is the measure of the flow of electricity through a circuit in amperes (amps) by a device known as an ammeter. You can check amperage by wiring an ammeter into the circuit (also called “in-series”), or you can detect current by clamping an induction meter around a wire.
