Electric circuits

Which of the following would happen if the switch was removed from the circuit above and the wires attached to the switch were connected?

• The wires would get longer.
• The light bulb would stay on. 
• The battery would get stronger.
•  The electricity would stop flowing.

The picture above shows an incomplete circuit.
How could a student make this a complete circuit?

• Add more batteries.
• Open the switch.
• Close the switch.
• Decrease the length of the wire.

Removing the battery from this circuit will cause the

• electricity to flow faster.

• circuit to overload.

• electricity to flow into the light.

• light to turn off.

The flow of electricity through a circuit is called a

• path

• current

• circuit

Electric energy _______ through a closed circuit.

• currents

• flows

• circuits

____________ allows electricity to flow.

• A conductor
• An insulator
• A magnet

____________ stops the flow of electricity.

• A conductor
• An insulator
• A magnet

To complete a circuit the switch must be

• unattached
• open
• closed

When the switch is closed, the light

• comes on
• stays off
• burns out

The plastic around the wire is

• a conductor

• an insulator

• a decoration
