An [[ammeter]] is a measuring device used to [[measure]] [[Electrical Current|electrical current]].
===About Ammeters===
: [[Ammeter]]s are added in [[Series Circuit|series]] to a [[circuit]] to find the [[Electrical Current|current]] flowing through the [[circuit]].
: An ideal [[ammeter]] has zero [[Electrical Resistance|resistance]] because otherwise adding an [[ammeter]] to a [[circuit]] would change the [[Electrical Current|current]].
: [[Ammeter]]s can be [[Analogue Ammeter|analogue]] with a needle pointing to numbers on a dial or it can be [[Digital Ammeter|digital]] with a number display.
