Two days ago, we learned about the flow of electricity. But today I got to light a lightbulb. The materials I used were a blade switch, a battery, a light bulb, and many wires. It total I used three wires. Two wires were attached to the battery. Then I attached one of the wire to one side of my light bulb. Then I took the other wire and attached it to the blade switch. Then I used one more wire to attach my light bulb to my blade switch. Then I just switched the blade, and then the light bulb lit up.
