Power Factor & Correction

Inside this lesson

Explain why a lagging power factor causes excess current draw and utility penalties
Compute the reactive power of an inductive load from real power and power factor
Determine the capacitance required to correct a load to a target power factor
Verify that real power is unchanged by adding a parallel capacitor while reactive power decreases
