In a single‑phase circuit, a capacitor used for power factor correction works like this:.
- The load (often inductive, like a motor) causes the current to lag behind the voltage low power factor.
- Adding a capacitor provides a leading current component, which cancels part of the lagging reactive current.
As a result:
- The power factor increases (moves closer to unity).
- The line current decreases (since reactive current is reduced, only active current remains significant).
Correct option:
The line current decreases and the power factor increases.
