Circuits
Just what is a circuit?
It’s like a circle
It’s like a race track that we run around
It’s like a board inside a computer
It’s to do with turning lights on and off
What IS a circuit?
When we turn a light on we close a circuit to let electricity flow to the bulb and light it up.
Light Circuit
A light circuit is usually made up of battery, wires and a bulb.
The circuit must be connected in order for it to work.
Problem!!If the circuit is on all the
time then eventually the bulb will burn out!
Solution
We put a switch into the circuit so that we can turn it on and off.
So there we have it …
A light circuit is used to bring electricity (power) to the light bulb to turn it on.
We need to have a switch in the circuit so that the bulb doesn’t burn out.
Your task …
Using the Brainbox equipment make a simple circuit with a bulb, a battery holder (and batteries) and a switch.
All done?
1. Show your circuit to a buddy2. Get your buddy to take a photo of
you and the circuit.3. Tell your teacher that you have
completed the task.4. Well done!
