How to measure apparent power?
Answer : Apparent power, usually represented as \( S \), is a combination of both real power (\( P \)) and reactive power (\( Q \)) in an AC (Alternating Current) system. It is measured in * ... know the power factor, which indicates how much of the apparent power is converted into useful work (real power)....
