How are series windings configured in a generator?

In a generator, series windings are configured by being connected in series to the armature through brushes. This configuration allows the current generated in the armature to flow through the series windings, thereby producing a magnetic field that enhances the overall output voltage of the generator.

When the load on the generator increases, the current flowing through the series windings increases as well, which in turn strengthens the magnetic field and boosts the voltage output. This relationship between the armature current and the generated magnetic field is fundamental to how series wound generators operate, as it ensures that they can adapt to varying load conditions.

The other configurations listed would not facilitate the intended interaction between the armature and the windings in a way that enhances the performance of the generator. For example, winding configurations connected in parallel would not provide the same level of magnetic field control as those connected in series.
