What happens when field current of generator windings increases?

When the field current of generator windings increases, it enhances the magnetic field strength within the generator. This leads to a higher induced electromotive force (EMF) and, consequently, an increase in the output voltage of the generator, provided the load remains constant. Additionally, the increased current can lead to greater power output, but it may also raise the risk of overheating and require careful management to avoid damage to the generator.
