A circuit is a path for electricity to move through. As electricity moves, or flows, the electricity could light a bulb, turn a fan, or charge your phone.

All circuits have the same basic parts, called components. One component is the power source. The power source pushes the electricity through the circuit. Circuits also have connectors. Connectors connect all the parts of the circuit and create the path or loop that the electricity travels through and are usually made of wire or another conductive metal. Another component is the load, or the thing being powered by the electricity in a circuit. It could be a light bulb, a fan, or any of the many electronic gadgets we use every day.  Finally, most circuits have a switch that completes and breaks the circuit.
