Electric current
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.[4]: 2 [5]: 622 The moving particles are called charge carriers, which may be one of several types of particles, depending on the conductor.
