POwer factor is the effective energy that can be utilized
for the work.
Power factor = Real power/Apparent power
A simple analogy:
It is like, a beer bottle with foam, the percentage of the
actual liquid is the real qty of liquid. The rest is foam.
Similarly, the real power is the qty of liquid beer, the
apparent power is the ful beer bottle with liquid as weel
as foam.
