Two examples of energy transfer:
In the home: An example of energy transfer in the home is the kettle. This home-located
item has electrical energy going into it while the energy out includes useful energy like heat
and not useful energy like kinetic, light and sound.
In the industry: An example of energy transfer in the industry is the conversion from kinetic
