Your chrome book charger cord is covered in a plastic coating. What is the benefit of this?

• The plastic converts electrical energy into thermal energy

• The plastic helps conduct electricity to the Chromebook

• The plastic is an insulator to protect humans from electricity

• The plastic makes sure that all the energy goes straight to the Chromebook

What would happen if the switch is turned off?

• The circuit will explode

• The lightbulb will turn off

• The battery will no longer work

• Nothing will happen

The TV is plugged into the wall and turned on. How is the energy transferred?

• Electrical is transferred to sound and light

• Chemical is transferred to light and mechanical

• Electrical is transferred to chemical and light

• Light and sound energy is transferred to mechanical

Explain why these charges are repelling away from each other

• Because they are opposite charges and they will attract

• Because they are both the same color

• Since there are no negative charges, the positives will connect

• Because like charges will repel away from each other
