Why is a capacitor a generator of lagging reactive power?

Click For Summary
SUMMARY

An ideal capacitor generates lagging reactive power, despite having a power factor of zero degrees leading, where current leads voltage. This phenomenon occurs because capacitors are utilized for reactive power generation in systems with inductive loads. The discussion highlights the role of capacitors in power factor correction and their importance in AC power systems. For further understanding, the insights provided in the linked articles on AC power analysis are essential.

An ideal capacitor has power factor of zero degree leading as current leads the voltage in capacitor.But it also means that capacitor is generator of lagging reactive power.What does that mean.How does it do so.Capacitor is used for reactive power generation at inductive load sites.
