Which device transforms electrical energy to mechanical energy?

• a flashlight

• a desk fan plugged into the wall

• a desk light pulled into the wall

• your chromebook when you turn it on

A cell phone is plugged into the wall using it's charging cable. What energy transformation is occurring?

• Electrical energy from the wall is transferred to the phone's battery where it is stored as chemical energy to power the phone

• Thermal energy from the wall is transferred to the phone's battery where it is stored as mechanical energy to power the phone

• Electrical energy from the phone is transferred to the wall outlet where it is stored as chemical energy to power the phone

• Radiant energy from the phone is transferred to the wall outlet battery where it is stored as mechanical energy to power the phone
