What is a circuit that only has ONE path for electricity to flow?

• series circuit

• closed circuit

• parallel circuit

• light bulb

What is a circuit?

A student constructs the circuit shown for a science demonstration. With the switches in these positions, which lights are on? (a)  

• All the lights

• 1 and 2 only

• 3 and 4 only

• none of the lights

Which statement is true?

• The light bulb will light up because the  circuit is complete.

• The light bulb will light up because the  circuit is broken.

• The light bulb will not light up because the  circuit is complete.

• The light bulb will not light up because the  circuit is broken.

Match the following

• A completed path that allows electricity to flow through it.

• Power Source

• Chemicals that react and give power. Example: batteries

• Open Circuit

• A path that is broken and won't allow electricity to flow through it.

• Closed Circuit

• A device that allows a circuit to be open or closed.

• Switch
