In a Wye connection, how are the coils arranged?

• A. Three coils with one end connected together
• B. Three coils connected in a triangle
• C. Coils connected in series
• D. Coils connected in parallel

Answer: (A)

In a Wye connection, the three windings are arranged so that one end of each winding is tied together at a common point, forming a neutral. The other ends connect to the three supply lines. This common junction is what creates the neutral node, allowing line-to-neutral voltages and giving the phase voltages of the windings, while the line-to-line voltage is √3 times the phase voltage. The other descriptions don’t fit a Wye: a triangle (delta) connects windings end-to-end in a loop with no neutral; linking windings in series or in parallel describes how windings are combined for voltage or current but not the star arrangement.
