Ammeter - Wikipedia
https://en.m.wikipedia.org/wiki/Ammeter
An ammeter (abbreviation of Ampere meter) is an instrument used to measure the current in a circuit. Electric currents are measured in amperes (A), hence the name. For direct measurement, the ammeter is connected in series with the circuit in which the current is to be measured.
