Question: 1 / 580

What device converts electrical energy into mechanical energy?

Generator

Transformer

Motor

The device that converts electrical energy into mechanical energy is a motor. Motors operate on the principle of electromagnetism, where electric current flows through coils of wire, generating a magnetic field that interacts with magnets or other electromagnetic fields. This interaction results in rotational motion, which is used in various applications, from small household appliances to large industrial machines.

In the context of the other options, a generator converts mechanical energy into electrical energy, making it the opposite of a motor. A transformer is used to change the voltage of an electrical current, transferring electrical energy from one circuit to another without converting it to mechanical energy. A capacitor stores electrical energy temporarily and releases it, but it does not convert energy into mechanical form. Thus, the function of the motor stands out as the correct answer in this scenario.
