Bulbs in series and bulbs in parallel

Circuit simulation

- click on the button ‘Intro’
- drag and drop bulbs, batteries and wires from the column on the left to the blue space to construct circuits (see some circuit arrangements below!)
- compare the brightness of the bulbs in each circuit as the number of batteries in series increases, the number of bulbs in series increases and the number of bulbs in parallel increases
- use this simulation to construct different circuits to investigate the brightness of different bulb in each circuit!
