Describe the energy transformations that take place in a battery-operated fan.

From Chemical energy (battery) to electrical energy (through wires) to mechanical energy

Explanation:

chemical energy in The battery is converted to electrical energy flowing in The wires, which is in turn converted to kinetic energy Of The fan blades. not all electrical energy is converted to kinetic energy, some are converted to heat energy

Answer: The fan converts electric energy into kinetic energy that does work, and it converts some electric energy into heat.
