Expert Answer:

The odd one out from the list is Electric Generator.
This is because in an electric generator electric energy is obtained from mechanical energy, whereas in other examples electric energy is converted to other forms of energy.
In playing a video, the electrical energy from the mains is converted to mechanical energy of rotating the disc which is then read as electric impulses in playing a video.
