Describe the energy transformation that occurs in a digital clock.

From electrical energy to kinetic energy.

Explanation:

Most digital clocks are made up of a set of four displays, consisting of seven luminous threads. To light each fillet, an electrical current of 10 milliamps is required. This occurs through electrical energy. Once inside the watch, the electrical energy is transformed into kinetic energy, which is the energy responsible for the movement of all the gears.
