Ammeter
Ammeter is used to measure
current I
in an electric circuit. In case of
voltmeter,
no ammeter can ever be ideal, and therefore all ammeters
have some small internal resistance. An ideal ammeter has a
zero resistance so that circuit in which it is kept is not
disturbed.
In More Simple terms an
ammeter is an electronic device that detects an
electric current
