'''Current''' is the amount of electrical charge flowing through an object, or through an electric circuit, at a given moment.  While moving charge is normally carried by [[electrons]], positive current is measured in the opposite direction from the flow of electrons, since electrons have a negative charge.<p></p>

Different objects have different [[Electrical_resistance|resistance]].  An object with high resistance, called an [[insulator]], will have a lower current flowing through it.  An object with low resistance, called a [[conductor]], will have a higher current flowing through it.

'''Current''' is typically measured in the [[SI]] unit of Amperes (<tt>A</tt>), often referred to as "amps".  <tt>1 A = 1 [[Coulomb]]/[[second]]</tt>

The word "current" appears in the phrases "direct current" ([[Direct current|DC]]) and "alternating Current" ([[Alternating Current (AC)|AC]]) though those phrases don't specifically refer to current, and could more commonly be considered to refer to [[volt|voltage]].
