Electricity and Magnetism

Static electricity is the buildup of electric charges on an object. Which of the following is the best way to create static electricity?

• banging two conductors together

• plugging in a plug to the outlet

• rubbing two insulators together

• turning on a light

Which object would be a conductor of electricity?

• iron nail

• wooden spoon

• rubber swing

• plastic bag

The diagram below shows a light bulb connected to a battery by a wire. What will happen with the light bulb?

• It will light up, because there is a power source.

• It will not light up, because there is no switch.

• It will not light up, because the pathway doesn't make a complete loop.

• It will light up, because the battery is positive.

Which of these is required to make a circuit?

• two or more batteries

• a closed loop

• a switch

• a lightbulb

Which would make the best insulator?

• aluminum

• plastic

• iron

• water

Marcus has a circuit that uses a battery to light up a light bulb. He needs three wires to make his circuit. He changes the circuit to have a paper clip attached to wire 2 as shown in the picture below.

What should Marcus predict will happen when he connects wire 3 to the paper clip?

• The wires will catch on fire

• He will get shocked.

• The light bulb will light up.

• The battery will burn.
