When a computer is plugged into an outlet and turned on, the electrical energy is turned into sound and light energy. However, not all of the energy is turned into sound and light. What happens to the energy that is not converted?

• The energy is stored in the device.

• The energy returns to the socket and back to the power plant.

• The energy disappears and is gone forever.

• The energy is lost as heat.
