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.


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.
