You will need to run the simulation on your computer; most systems will simply open the simulation, but you may need to download it and run it to get the simulation to work. The PheT website is well known and safe. Downloading and using the simulations on this site will not harm your computer. 2. Select the simulation labeled "Intro". Select "Conventional" under the heading "Current" in the options on the right hand side. Drag and drop the circuit components on the left hand side to create a simple circuit that contains a battery, a lightbulb, and a switch. Use the wire (as many pieces as needed) to connect the other components. Sketch the circuit that you constructed below
