Power factor and three-phaseQuestion 1166 of 1506

A motor load is mostly inductive. What do we call its power factor?

  1. Leading
  2. Lagging
  3. Unity
  4. Reversed
Show answer

Correct answer: Lagging

When a circuit is mostly inductive, its current lags the voltage, so the power factor is lagging.
