apparent power

(electricity)
The product of the root-mean-square voltage and the root-mean-square current delivered in an alternating-current circuit, no account being taken of the phase difference between voltage and current.

Apparent Power

 

a quantity that is equal to the product of the effective values of the periodic electric current I in a circuit and of the voltage U across the terminals of the circuit: S = UI. For a sinusoidal current (in complex form), = U̇İ, where is the complex effective value of the voltage and İ is the conjugate of the complex effective value of the current. S͂ = P + jQ, where P is the active power and Q is the reactive power; for inductive loads, Q > 0, and for capacitive loads, Q< 0. Apparent power is measured in volt-amperes.

The captured data was then analysed in MATLAB[R] to conduct a multi-criteria assessment of lamps based on different perspectives including harmonic current injection, THD, power factor, active power consumption, and stabilisation time, fundamental and non-fundamental apparent power and were then compared to each other to yield a better understanding of their characteristics.
Nevertheless, due to the fact that the classical apparent power and its resolution are defined under sinusoidal and balanced conditions, they did not attain their goals in the case of nonsinusoidal and/or unbalanced conditions.
