The three essential parts of any electrical circuit are: a power source (like a battery or generator), a load (like a light bulb or motor) and connectors (wires) to join them together.

A fourth part, that is always a very important thing to have in most circuits, is a control device such as a switch, circuit breaker or fuse.
