In this investigation, you will build a variety of working circuits. You must include a switch in each circuit you build. The circuit components are provided, but you must place them in the correct configuration for the circuit to safely work. Once the circuit is working, you can measure the voltage and current at different points on the circuit. You can also explore what happens when a load (light bulb) in the circuit breaks. Click on each tab at the top for a different circuit building challenge.
