The ends of the winding associated with the transformer are commonly labeled in which sequence?

Explanation:
Labeling the ends of transformer windings in a simple, sequential way helps you track where each coil starts and ends and how its polarity is oriented. In this convention, one winding has ends labeled A and B, and the other winding has ends labeled C and D. This A-B-C-D sequence provides a clear, consistent map of the two windings so you can connect them correctly for series or parallel operation and preserve the intended phase relationship when wiring or testing the transformer. Using other schemes (reversing the alphabet or using numbers) would be less intuitive and prone to confusion in diagrams and schematics, so A-B-C-D is the standard and most recognizable labeling.
