Electricity & Magnets

A student built two simple circuits by attaching wires to a battery, a bulb, and a switch. In diagram 1 the switch is closed and in diagram 2 the switch is open. Label each of the diagrams correctly based on if the bulb will light up.

• The bulb will light.

• The bulb will not light.

Look at the diagram below. What kind of circuit is this?

• open circuits

• closed circuit

• short circuit

• parallel circuit

• series circuit

Look at the circuits below. Select the two pictures that show a circuit that has a continuous flow of energy that would allow the light bulb to emit light.

• Top left circuit

• Top right circuit

• Bottom left circuit

• Bottom right circuit

A group of kids are playing on the slides at the park playground. As they go down the slide, they notice that their hair would stick up in all directions. This likely happens because:

• Static electricity was occurring because the slide had a positive charge and the kids had a positive charge.

• Static electricity was occurring because the slide had a negative charge and the kids had a negative charge.

• Static electricity was occurring because the slide had a positive charge and the kids had a negative charge.

• Static electricity could not happen in this situation because there were no positive or negative charges.

When the lamp is plugged into the wall and the light bulb is turned on, how is energy transformed in this example?
