For electricity to flow, you need a circuit. There are three parts to a circuit: a source, a connector and a recipient. The source can be a battery, the connector a wire and the recipient a bulb. If you connect these three things in a straight line--battery to wire to light bulb--no electrons will flow. The bulb will not be lit. Why not? Because the circuit is open. The path needs to continue back to the positive end of the battery or else the electrons won’t move. When the circuit is closed, electrons flow, but if the circuit opens, the current stops. A closed circuit that has just one source and one recipient is called a simple circuit.
