In this activity, students explore the concept of variable resistance by using a simple electrical circuit.
By the end of this activity, students should be able to:
- construct simple electrical circuits to explore variable resistance
- show that the flow of electric charges can be controlled and modified by changing the length of wire or strip of carbon that conducts the current.
