Why do we use capacitors for power factor correction and not
A lot have mentioned that we use capacitors to correct power factor because loads are inductive, like motors. I''d like to expand a bit on the relationship between the two because your question shows good understanding of the basics but you''re missing a few key points which will make the whole thing come together.
