Damian felt a shock from electricity when he touched the metal knob on a door after walking across the carpet in his bedroom. Which statement correctly describes the type of electricity that caused the shock Damian received?

• Static electricity caused the shock when Damian's hand interrupted the steady flow of electrons traveling through the door knob.

• Static electricity caused the shock as a buildup of electrons were released when Damian touched the door knob.

• Current electricity caused the shock as a buildup of electrons were released when Damian touched the door knob.

• Current electricity caused the shock when Damian's hand interrupted the steady flow of electrons traveling through the door knob.

A student designs a simple electric circuit as shown in the diagram.

Which statement BEST explains whether the circuit will light the light bulb?

• The circuit will light the light bulb because it has a power source in the light bulb and place to store electricity in the battery.

• The circuit will not light the light bulb because the wires are connected to the light bulb which prevents electricity from flowing.

• The circuit will not light the light bulb because it does not have a switch to provide a starting source of energy for the light bulb.

• The circuit will light the light bulb because it has a power source in the battery and a way for the energy to travel through the wires.
