When the winding ends are brought out of the core they are labeled __________.

Explanation:
Labeling winding terminals with simple letters provides a clear, universal way to identify the ends of two windings when they are brought out of the core. Using designated ends such as A and B for one winding and C and D for the other makes diagrams, wiring, and polarity checks straightforward. It’s easy to reference in schematics and ensures consistent communication across diagrams, tests, and connections. Other labeling schemes like numbers, Roman numerals, or less common letter sets aren’t the standard, so they can cause confusion or misconnection. That’s why the common practice is to use four distinct lettered terminals, typically A, B, C, and D.
