IEVref: 131-11-39 ID: Language: en Status: Standard Term: complex power Synonym1: complex apparent power [Preferred] Synonym2: Synonym3: Symbol: $\underset{_}{S}$ Definition: under sinusoidal conditions, product of the phasor $\underset{_}{U}$ representing the voltage between the terminals of a linear two-terminal element or two-terminal circuit and the complex conjugate of the phasor $\underset{_}{I}$ representing the electric current in the element or circuit $\underset{_}{S}=\underset{_}{U}\underset{_}{I}*$Note 1 to entry: Complex power is equal to $P+\mathrm{j}Q$, where P is active power and Q is reactive power. Note 2 to entry: The coherent SI unit for complex power is voltampere, VA.
