Type A regulator is associated with which part of the transformer?

A Type A regulator is specifically associated with the series winding of a transformer. This type of regulator is designed to adjust the output voltage by controlling the amount of power supplied from the primary winding to the secondary winding through a series connection. In essence, it ensures that fluctuations in load or input voltage have minimal impact on the output voltage by dynamically altering the energy flow through the series winding to maintain a stable output. This regulation is essential for applications where consistent voltage is critical, such as in electrical devices and systems requiring precise voltage levels.

The other windings mentioned, like primary and secondary, have their own roles in the operation of the transformer but do not encompass the specific function attributed to Type A regulation. For example, the primary winding is where the input voltage is applied, while the secondary winding delivers the transformed voltage to the load.
