A secondary school resource produced with the support of the Institution of Engineering and Technology to accompany this year's CHRISTMAS LECTURES.
Conductive dough circuits are an interesting and surprising way to introduce students to circuit building, resistance and conductivity. In this activity students will explore the concept of resistance and how resistance varies for different materials. They will measure voltage and current using an ammeter and voltmeter and use the formula V=IR to calculate resistance. Finally they will investigate how resistance varies with length and width of the conductor.
