apparent power

[ə′pa·rənt ′pau̇·ər]
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.
