Which of the following components converts electrical energy into mechanical energy?

The component that converts electrical energy into mechanical energy is a motor. Motors operate based on the principle of electromagnetism, where they use electric current to create magnetic fields that interact with permanent magnets or other coils, resulting in the movement of a rotor. This rotational movement is what we identify as mechanical energy.

In practical applications, motors can be found in various devices and machinery, from household appliances like fans and washing machines to industrial equipment. By utilizing the energy supplied by electricity, motors provide the necessary force and motion to perform work.

The other components listed serve different functions. Generators convert mechanical energy into electrical energy, transformers are used to change the voltage of electrical energy without converting it to mechanical energy, and resistors limit the flow of electrical current but do not convert energy, instead dissipating it as heat. Each of these components plays a crucial role in electrical systems, but the specific function of converting electrical to mechanical energy is the defining characteristic of a motor.
