What is the primary winding connected to?

Explanation:
The primary winding is the input side of a transformer; it is connected to the input voltage source. When AC is applied to this winding, it creates a changing magnetic flux in the core, which induces voltage in the other winding (the secondary) to supply the load. The winding that feeds the output/load is the secondary, and terms like rotor or permanent magnets belong to motors or generators, not transformers. So the primary winding is connected to the input voltage.
