A PATH along which electricity can flow is a ___________________?

• light bulb

• switch

• insulator

• circuit

What is a material that allows electricity to pass through easily?

• parallel circuit

• rubber band

• conductor

• electron

this circuit is .....?

• open
• parallel
• closed
• The cutest little circuit evah!

The plastic covering is there to:

• Provide a conductor for electrical energy to flow.
• Provide an insulator so that electrical energy will not pass outside of the wires.
• Provide a conductor so that electrical energy can NOT flow.
• Provide an insulator so that electrical energy can flow.
