The conventional direction of current, also known as conventional current, is arbitrarily defined as the direction in which positive charges flow. In a conductive material, the moving charged particles that constitute the electric current are called charge carriers. In metals, which make up the wires and other conductors … See more An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume. … See more The conventional symbol for current is I, which originates from the French phrase intensité du courant, (current intensity). Current intensity is … See more In alternating current (AC) systems, the movement of electric charge periodically reverses direction.
