🔍 Key Concepts

• Three-phase alternator connections: difference between wye (Y) and delta (Δ) in terms of line vs phase voltage and current • The relationships for line voltage and phase voltage in wye vs delta connections • How line current and phase current differ between wye and delta connections

💭 Think About

• First recall in a wye (Y) connection: how does line voltage relate to phase voltage, and how does line current relate to phase current? • Then, for delta (Δ) connection: which quantity (voltage or current) stays the same from line to phase, and which one is multiplied by √3? • Look at each choice and ask: is it describing a relationship that belongs to wye or to delta? Eliminate any that clearly describe wye behavior.

✅ Before You Answer

• Be sure which connection (wye or delta) has line voltage = √3 × phase voltage • Be sure which connection (wye or delta) has line current = √3 × phase current • Check which option correctly matches the relationship that is unique to delta, not shared with wye.
