Improving a lagging load power factor by connecting a shunt capacitor primarily reduces the source?

  • AReactive current component
  • BReal power demanded by the load to zero
  • CSupply frequency
  • DLoad resistance to zero
Report an error
Correct Answer: A. Reactive current component
Explanation: The capacitor supplies leading reactive current locally, reducing the lagging reactive current drawn from the source while the load real-power requirement is essentially unchanged.
