Physical science: circuits

Build electric circuits using batteries, light bulbs, resistors and other components. Add meters to measure the voltage, current and resistance. Investigate Ohm’s Law. Discover how to find the total resistance of a combination of resistors. Test your understanding by answering five assessment questions.

Basic electric circuits part 2: measuring current with a multimeter - practical activity

In this practical activity, students measure the amount of current flowing in series and parallel circuits and explore the effects of adding different numbers of globes into the circuits. This experiment is the second of three experiments on basic electric circuits; in the first, students investigate series and parallel ...

Energy resources: batteries part 1: the power delivered by a battery - practical activity

In this practical activity, students measure the power delivered by a battery to a globe. They may also measure and compare the power drawn from the battery by different devices, such as an LED. This experiment is the first of four experiments on energy resources; in the second, students measure and compare the power delivered ...

Energy resources: How many blades should a wind turbine have? - practical activity

In this practical activity, students measure the electrical power delivered by a model wind turbine. They predict then investigate how many blades on the turbine deliver the greatest amount of power. The activity is the third of four experiments on energy resources; in the first, students measure the electrical power delivered ...

Energy resources: What power can you get from a solar panel? - practical activity

In this practical activity, students measure and compare the power delivered by model solar cells connected in series and in parallel. It is the fourth of four experiments on energy resources; in the first, students measure the electrical power delivered by a battery, in the second, students measure and compare the power ...

Energy resources: batteries part 2: connecting batteries in series and in parallel - practical activity

In this practical activity, students measure and compare the voltage, current and power delivered by batteries connected in series and in parallel. This experiment is the second of four experiments on energy resources; in the first, students measure the electrical power delivered by a single battery, in the third they measure ...

Measuring Current

In this simulation students elect to measure the current in a circuit containing either one or two light bulbs in series and observe the relationship between current and brightness of the light bulbs. Students drag and drop a battery, switch, ammeter and light bulbs into position on a circuit.
