3 Phase Systems

Question 1

The impedance angle is different than the power factor angle, and the current to voltage angle; t or f.

Answer 1

F. They’re the same.

Note: can’t use the pf angle (aka
Phase angle) to calculate V instantaneous as voltage isn’t related to the power factor angle. It always follows it’s own sinusoidal waveform that is constant throughout the world (if it’s made by moving current through a coil and rotating the coil around a conductor, ie like an alternator; otherwise, possible to
Produce non sinusoidal ac waves).
