ammeters
Electrical flow measurers
Ammeters are instruments that measure electric current, calibrated in amperes.
The word combines ampere and meter.
An ammeter connects in series with a circuit to measure the current flowing through it: The ammeter showed a reading of 2.5 amps.
Digital ammeters have largely replaced older analog models with needle displays.
