What device transforms electrical energy into mechanical energy?

The device that transforms electrical energy into mechanical energy is a motor. Motors work by converting electrical energy into mechanical motion through electromagnetic principles. When electric current flows through the motor’s windings, it creates a magnetic field that interacts with magnets or other coils within the motor, resulting in rotational motion. This transformation is fundamental to many applications, such as powering machinery, tools, and various appliances.

Generators, on the other hand, do the opposite by converting mechanical energy into electrical energy. A transformer is used to change the voltage levels of alternating current electricity without converting it to mechanical energy, and a capacitor stores electrical energy in an electric field but does not transform it into mechanical energy.
