Message: <blockquote data-quote="Cpyder" data-source="post: 5333241" data-attributes="member: 599745">Electric current is the flow of electric charge. The electric charge may be either electrons or ions. Ions can be positive.  A flow of positive charge gives the same electric current as an opposite flow of negative charge. So yes, current can flow either + to - or - to +.  Referring to car audio and how it's hooked up, electrons flow -  to +.Because the electron carries negative charge, the electron motion in a metal is in the direction opposite to that of conventional (or electric) current. While it would make more sense to draw current arrows in the direction of what is actually flowing, convention dictates that this not be the case.</blockquote>
