The components of a simple circuit are -------, ------ and -----------

​When you turn on a flashlight, electricity makes the bulb light. To make the flashlight work, electric charges must move from one place to another. The charges travel along a path.

​Electrons flow along a path called a circuit. A circuit is composed of a source of electrons, the load, the wire and a switch.

​The source of electrons is usually a battery, while the load is any objects powered by electricity such as a light bulb on a buzzer.

​Wires connect one components of the circuit to another so that electric current

flows. Wires must be good conductors of electricity; they should be made of materials

that will allow electric current to flow through it.

​A switch conducts the flow of current in a circuit. The circuit should be close for electric current to flow in the circuit.
