We learned about a lot of different things that can relate to this lightbulb. First of all, the light is off. When you turn the switch on the back, the circuit closes and tells the electrons inside the wire to start moving, creating current. The type of current that runs through this lightbulb is alternating current, which means the electrons are moving back and forth to create current. In order to prevent a fire from the energy that is converted to heat in the wires and not used in the filament of the lightbulb, there is a fuse right behind the plug where I plugged this light in. That fuse is a glass tube with a small metal bar through the center. When the wire gets too hot, the wire inside the glass tube breaks which breaks the circuit, even if the light's switch is on.
