Is wood a conductor or insulator?

• Conductor
• Insulator

What is the difference between a conductor and an insulator?

• An insulator allows electricity to flow through it easily and a conductor does not
• A conductor allows electricity to flow through it easily and an insulator does not.
• An insulator is magnetic and a conductor is not
• A conductor is magnetic and an insulator is not

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.

You know that the object connected to the wires is a conductor because:

• The light bulb is glowing bright.
• It's a complete circuit.
• It's a closed circuit.
• The object is shiny.
