Ammeters are always connected in a circuit and have a very low resistance to current flow. An ammeter (short for ampere metre) is a tool for determining the current in a circuit. Electric flows are measured in amperes, therefore the name originates from that (A). Instruments that measure ...
The presence of current is detected using galvanometer. The intensity or strength of current is measured using an ammeter.
