Now your turn. On a piece of paper draw a circuit with one cell, a bulb and a switch (open). When you have finished click on the finished button below.
This is what the circuit should look like with the switch open. For this circuit to work we would have to close the switch. Did you get it right?
How could we make the bulb brighter. Think about it and then click on answer.
Next time we look at circuits it will be slightly harder, but just remember what you have learned.
