You Searched For: Ammeters

Ammeters, also known as current meters, are metered instruments that measure current flow in amperes. These devices provide information about current draw and current continuity in order to track loads and trends. With an analogue ammeter, current levels are displayed on a dial, usually with a moving pointer or needle made of a soft iron. Digital ammeter designs use a shunt resistor to produce a calibrated voltage proportional to the current flowing.
