Learning time​

Kids learn by watching short, engaging video lessons.

A simple electrical circuit is made-up of a battery, wires that connect to the positive and negative ends of the battery, and a light bulb or any other device that uses electrical energy. Interestingly, electricity will only travel around the circuit that is complete. This means that there are no gaps in the circuit. If you wish to create a gap in the circuit, you can use a device called a switch. A switch will create a gap in the circuit that can be used to turn the light bulb or device in the circuit on and off. If you wish to make the bulb in the circuit brighter, you can add more batteries. This will increase the amount of electrical energy within the circuit.
