Insulators and Conductors

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

• wood

• plastic

• metal

• cloth

What object would best complete this circuit?

• a battery

• a peice of yarn

• a cotton swab

• a paper clip

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 object is shiny.

• It's a closed circuit.

• The light bulb is glowing bright.

• It's a complete circuit.
