ELECTRICITY: ELECTRICAL CIRCUIT: simplified animation of the movement of electrons (the opposite of conventional current) in a simple electric circuit consisting of a battery, a switch and a light bulb.
ELECTRIC CURRENT is the flow of charge. Conventionally this is the flow of positive charge. However, in a simple circuit such as that illustrated the current in the wire is composed of electrons that flow from the negative pole of the battery (the cathode at the bottom of the battery) and return to the positive pole (the anode at the top of the battery, marked by a +). The diagram at the left shows the same circuit as the one in the animation but in a standardised diagrammatic form (i.e. it's a circuit diagram).
