Electric current is defined as the movement of electrical charges.

Electric current in a metal conductor is carried by a wire. This wire has been specifically adapted to carry this current.

Electric current is measured using an ammeter. It is a device that is connected in series in an electric circuit to measure the flow of current passing through it.

Electric current is produced when charged particles, such as electrons, move through a conductive material, creating a flow of electric charge. The movement of these charged particles generates an electric field, leading to the flow of current in a closed circuit.

Electric current from a generating plant is typically alternating current (AC), which flows back and forth in a rapid and regular manner. This AC current is then transmitted through power lines to homes and businesses for use in electrical appliances and devices.
