glue the wire to the nail

Wrap the wire around the nail less times

Wrap the wire around the nail more times

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.

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.
