The picture shows an incomplete circuit with a battery, a piece of wire, and a light bulb. Different points of the circuit are labeled A, B, C, and D.

Where does the loose wire need to be attached for the light bulb to work?

• A. point A

• B. point B

• C. point C

• D. point D

Which of these best describes why many electrical wires have plastic coatings on them?

• A. Plastic conducts electricity, so it helps the electricity flow through the wire.

• B. Plastic does not conduct electricity, so it helps the electricity flow through the wire.

• C. Plastic conducts electricity, so it keeps a person from getting shocked when handling the wire.

• D. Plastic does not conduct electricity, so it keeps a person from getting shocked when handling the wire.

If the paper clip in the diagram is replaced with a plastic spoon, what will happen?

• A. The wires get hot.

• B. There is no change.

• C. The bulb is dimmer.

A ladder made of which material would be the most dangerous to use if someone were working around power lines?

• A. fiberglass

• B. metal

• C. plastic

• D. wood

Which is true?

• A. Insulators easily conduct electricity.

• B. Conductors block the flow of electricity.

• C. Insulators allow current to flow through them.

• D. Conductors allow electrons to flow through them.

The plastic coating was stripped of the end of the piece of wire shown in the image. Why must the plastic be removed before this wire is used in an electric circuit?

• A. So the wire can be bent and fit into the circuit.

• B. To prevent the circuit from becoming overloaded.

• C. Because the plastic makes the wire too thick to use in a circuit.

• D. So that electric current can pass between the copper wire and other parts of the circuit.

Which circuit allows for the flow of energy through the entire circuit?
