Conductors and Insulators

What is the main characteristic of conductors?

• Preventing the flow of electric current

• Generating electric current

• Absorbing electric current

• Allowing the flow of electric current

What is the main characteristic of insulators?

• Insulators conduct electricity easily.

• Insulators are good conductors of heat.

• Insulators are magnetic materials.

• Insulators do not conduct electricity easily.

Which of the following is a good conductor of heat?

• Plastic

• Metals

• Glass

• Wood

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.
