An ammeter is a device used to measure the amount of electric current flowing through a circuit. It is usually used by electricians and engineers to ensure that a circuit is functioning correctly and safely. The ammeter measures the amount of current by measuring the flow of electrons through a wire, and the reading is displayed on a dial or digital display. Ammeters are commonly found in electrical panels or control rooms, and are also used in scientific research, manufacturing, and many other applications.
