Bulbs in series and bulbs in parallel
Observe how the arrangement of bulbs affects the brightness of each bulb and why the brightness of the bulbs differ!
Explore the electrical conductivity of various objects using the simulation below!
1) click on the button ‘Intro’
2) 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!)
3) 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
4) use this simulation to construct different circuits to investigate the brightness of different bulb in each circuit!
