Question

A factory load has lagging power factor 0.6 (inductive). To improve PF to unity, one should add:
  1. A
    More inductors in series
  2. B
    A capacitor in parallel with the load
    Correct
  3. C
    A resistor in parallel
  4. D
    A transformer

Correct answer

A capacitor in parallel with the load

Explanation

Inductive loads have lagging current (current lags voltage). A parallel capacitor draws leading current that compensates the lagging component of the load current → net PF approaches unity. This is power factor correction, widely used in industrial power systems.
