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
• the electricity to flow into the light
• the light to turn off

A student could increase the number of paper clips the electromagnet could pick up in all the following ways EXCEPT:

• add more batteries
• increase the number of coils
• replace the battery with a more powerful battery
• increase the length of the wire

Electricity that flows in a closed path is called a

• path
• current
• circuit

The flow of electricity in a circuit-

• current
• flow
• circuit

Magnetism created by an electric current

• electricity
• electromagnetism
• wind energy

____________ 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
