What is the other winding called in a regulator that is connected to the induced voltage?

The winding that is connected to the induced voltage in a regulator is referred to as the series winding. This winding plays a critical role in coordinating the voltage regulation of electrical systems. It is connected in series with the load and, as the load changes, the current flowing through the series winding adjusts the magnetic field produced by it. This adjustment helps in maintaining a consistent output voltage under varying load conditions.

In contrast to the series winding, the other options refer to different types of windings or roles within electrical systems. The exciting winding generally refers to windings used to create magnetic fields in machines such as generators or transformers. The shunt winding is typically connected parallel to the load and is used primarily for voltage regulation; it does not directly connect to the induced voltage in the same manner as a series winding. The term induced winding is not commonly used in electrical engineering contexts. Therefore, the series winding is the most accurate term for the winding that connects to the induced voltage, as it actively regulates voltage levels in response to load changes.
