An electric current is a flow of charged particles, [1] [2] [3] such as electrons or ions, moving through an electrical conductor or space. It is defined as the net rate of flow of electric charge through a surface.
The instantaneous electrical current, or simply the current I, is the rate at which charge flows. The direction of conventional current is taken as the direction in which positive charge moves. In a …
