Have you been introduced to simple circuits at school? if you have you might like to try this quiz. There are 9 circuits. Each circuit has batteries/cells (all of the same strength) and light bulbs (all identical). I would like to know which bulbs are lit and which are unlit and if some lit bulbs are dimmer than the other lit bulbs.
When you have worked out the answers you can check them against my answers by going to the Check button at the bottom of this page.
