ammeter

Measures electrical flow

An ammeter is an instrument for measuring electric current, typically calibrated in amperes.

It connects in series with a circuit so that current flows through it: The ammeter showed a steady draw of 2.5 amps.

Ammeters range from simple analog gauges to precision digital devices used in laboratories and industrial settings.
