An LED lightbulb has an energy efficiency of 89%. This means that 11% of the electrical energy that goes into an incandescent lightbulb is used to produce light energy.
Which statement best explains what happens to the other 11% of the electrical energy that goes into the lightbulb?
The leftover electrical energy is destroyed
The leftover electrical energy is transferred into heat energy
The leftover electrical energy is transferred into chemical energy
The leftover electrical energy is transferred into potential energy
