In the classroom, the lights are actually turning on and off 60 times each second, much faster than our eyes can see, so the lights appear to be constantly on. The simulation slows down the current so we can observe it. 1. Build a series circuit with one light bulb, and instead of the battery use the "AC Voltage" power source. Include the screenshot here. [Screenshot] 2. Observe the flow of electrons. Describe the actions of the electrons in your AC circuit. [Answer] 3. Click on the " Current chart" tool and place the sensor on your wire.
