From which part of a generator is the output voltage taken to supply the load?

• A. Rotor
• B. Stator
• C. Armature
• D. Field winding

Answer: (B)

The output voltage of a generator is taken from the stator, which serves as the stationary part of the generator. In an alternating current (AC) generator, the stator windings are where the electric current is induced as a result of the magnetic field created by the rotor's movement. The rotor rotates inside the stator, which typically consists of multiple coils of wire. As the rotor spins, it creates a changing magnetic field that induces an electrical current in the stator windings. This induced current is then taken off from the stator to supply power to external loads.

In contrast, the rotor is responsible for creating the magnetic field but does not directly supply output voltage. The armature can refer to the component that carries the current in a generator, typically housed in the stator in AC machines, but proper terminology usually designates the output voltage source as originating from the stator itself. Field windings are also essential, as they establish the necessary magnetic field for operation but are not the source of the output voltage for external loads.
