Electric Circuit
Electricity moves or flows from one place to another through wires and other objects. For electricity to flow, it needs a continuous path. We call this path an electric circuit. This means that there should be no break or gap in the path or circuit. To use this electricity, we use objects, such as light bulb, so that the electrical energy can be changed into heat, sound or light energy.

An electric circuit needs a power supply. This can be a battery, or electricity from a generator. A circuit also needs wires for electricity to flow through.

The electricity used in the light bulb flows along the wires. It is supplied by the battery. This is called an electric current.

Electric circuits are made up of a number of different parts that we call components. The components include batteries, torch bulbs and wires. The circuit that you have connected in the activity above shows that the components must be connected to one another for electric current to flow through.
