Which electrical machine converts electrical energy into mechanical energy?

Which electrical machine converts electrical energy into mechanical energy?

• A. Electric Generator
• B. Transformer
• C. Battery
• D. Electric Motor

Answer: (D)

An electric motor transforms electrical energy into mechanical energy. When current flows through the motor’s windings in a magnetic field, forces act on the conductors and create torque, causing the rotor to rotate. This is the direct conversion of electrical power into rotational mechanical work. For contrast: a generator does the opposite, turning mechanical energy into electrical energy. A transformer changes voltage and current levels of AC power without changing its electrical/mechanical form. A battery stores chemical energy and provides electrical energy, which can drive a motor, but the battery itself isn’t converting electrical energy into motion.
