: '''Current''' is [[measure]]d using an [[Ammeter]].
: The [[SI Unit|units]] of '''current''' are [[Amp|amperes]], which are also called [[amp]]s ([[A]]).
: A '''current''' in a [[wire]] is a flow of [[electron]]s which are [[Negative Charge|negative]]ly [[Electrical Charge|charge]]d [[particle]]s.: Conventional '''Current''' flows from [[positive]] to [[negative]]. This is because [[electricity]] was discovered before [[scientist]]s knew about [[electron]]s.: In a [[salt]] [[solution]] '''current''' is the flow of both [[Positive Charge|positive]] and [[Negative Charge|negative]] [[ion]]s.
