Electrician Red Seal · Question
A three-phase wye-connected generator is supplying a balanced resistive load. The line-to-neutral voltage is measured at 240 V. What is the approximate line-to-line voltage?
In a wye-connected system, the line-to-line voltage is approximately 1.732 times the line-to-neutral voltage. Therefore, 240 V * 1.732 ≈ 415.68 V, which is appr

Question: A three-phase wye-connected generator is supplying a balanced resistive load. The line-to-neutral voltage is measured at 240 V. What is the approximate line-to-line voltage?
Answer options:
- 208 V
- 240 V ✅ 416 V
- 480 V
Correct answer: 416 V
Explanation: In a wye-connected system, the line-to-line voltage is approximately 1.732 times the line-to-neutral voltage. Therefore, 240 V * 1.732 ≈ 415.68 V, which is approximately 416 V. The other options are incorrect based on this relationship.
