Power factor and three-phaseQuestion 1035 of 1506

In a delta-connected three-phase load, how are the line voltage and the phase voltage related?

  1. They are equal
  2. Line voltage is √3 times phase voltage
  3. Line voltage is half the phase voltage
  4. Line voltage is three times phase voltage
Show answer

Correct answer: They are equal

Each pair of lines connects directly across one winding.
