Which configuration is also known as a wye connection?

• A. Delta
• B. Wye
• C. Rectangle
• D. Triangle

Answer: (B)

In three-phase systems, the wye (star) connection is formed by tying one end of each winding to a common neutral point, while the other ends become the three external lines. This setup gives line-to-neutral voltages and often uses a grounded neutral; the line-to-line voltage is sqrt(3) times the line-to-neutral voltage. The term wye is simply another name for this star configuration, which is why this option is the best choice. The delta arrangement is a different layout with windings forming a closed triangle and usually no neutral, and rectangle/triangle are not standard terms for three-phase connections.
