Electric current

An electric current is a flow of charged particles, such as electrons or ions, through an electrical conductor or space. It is defined as the net rate at which electric charge flows through a surface.: 2 : 622 The moving particles are called charge carriers, which may be of several types, depending on the conductor. In electric circuits, the charge…
