Explaining Electric Current

Comments (0)

Produced by the Learning and Skills Improvement Service, this resource is a kinaesthetic activity in which students experience being part of a 'circuit'. A rope loop is passed around the group to represent the current flowing in a circuit. One student, the power supply, adds movement to the rope. The students see that all of the rope (current) moves instantaneously and that it is the power supply that is doing work in adding energy to the circuit. The activity can also be used to introduce the idea of electrical resistance.

HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
