Series circuits are described as simple. Fairy lights are used as an example. An explanation is given of how any break in a series circuit results in no flow of electricity. Parallel circuits are then described. A go-kart track with two routes is used as a model, before a hair-dryer is given as an example. An explanation is given of how a break in a parallel circuit only results in components on that branch not working.

Students could use this clip to look at the differences between series and parallel circuits. They could illustrate the differences using some everyday examples.
