What is Power Factor and why is it important?
In other words, we can say that 80% of the power is useful power which is also known as real or True Power, and the rest 20% of power is Reactive Power used by reactive elements in the circuit. Because the Electric Company must supply total apparent power (kVA) to the consumer and in return, consumers pay them only for real power (kW).

When should I use a low ESR capacitor
The requirement for "low-ESR" capacitors normally arises in output filters of switching power supplies, where the frequency is relatively high (kHz to MHz). It''s less important in mains filters (including the input filter of a SMPS) where a large capacity electrolytic tends to have a proportionally small ESR so that 100Hz or 120Hz ripple is not …
