Electricity and Circuits

A complete circuit is an open circuit

• True
• False

Label the circuit

• closed circuit
• complete circuit
• incomplete circuit
• working circuit

A light bulb will shine brighter when

• An extra light bulb is added to the circuit
• An additional battery is added
• A smaller battery is used
• The switch is open in the circuit

• Series circuit
• Parallel circuit
• open circuit
• not a circuit

What would happen if the switch was opened?

• nothing, the light bulbs would still work because there is a complete path
• The light bulbs would not work because the path was broken
• the battery would loose energy
• the wires would be cooled from air

The on switch shows

• An open circuit where electricity can flow
• A closed circuit that is also called complete
• not related to circuits
• An incomplete circuit that does not allow electricity to flow

This circuit

• has one path for electricity to flow
• has two paths for electricity to flow
• has three paths for electricity to flow

In which of the following circuits will all of the remaining light bulbs go out if bulb 3 burns out?

• 
•

Which object does NOT conduct electricity?

• copper wire

• iron nail

• salt water

• wood

What happens if there is a break at any point in a series circuit?

• no current flows

• current flows through an alternative path

• resistance goes to infinity

• current reverses direction
