Ammeter, instrument for measuring either direct or alternating 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 the major portion.
What does an ammeter tell you?
An ammeter measures the electric current in a circuit. The name is derived from the name for the SI unit for electric current, amperes (A). In order for an ammeter to measure a device's current, it must be connected in series to that device.
How does an ammeter measure current?
Ammeters work to measure electrical current by measuring the current through a set of coils with a very low resistance and inductive reactance. ... If the ammeter were connected in parallel, the path may become short-circuited such that all the current will flow through the ammeter instead of the circuit.
