Unit 5: Electrical conductors and insulators

What is a conductor?

• Material that does NOT transfer electricity.

• Materials that are connected to circuits.

• Materials that transfer electricity.

A great conductor of electricity is:

• wood

• plastic

• metal

• cloth

An insulator is a material that:

• Transfers thermal and electrical energy

• Transfers electrical energy and slows thermal energy

• Slows electrical energy and allows thermal energy to pass

• Does not allow electrical energy to transfer

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.

Tatrys knows that the light bulb will turn on because the circuit:

• includes an insulator.
• is an open circuit.
• makes a complete path.
• includes a battery.

Which is NOT an insulator.

• Wool
• Plastic
• Copper
• Glass

Water is a insulator.

• True
• False

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

A great conductor of electricity is:

• wood

• plastic

• metal

• cloth

What is pure water?

• Is distilled water.

• Is water that only have hydrogen and oxygen as its components.

• Is water that we drink.

• Is water with salts and other substances.
