Formula for complex power
WebComplex power, denoted by S, is the vector sum of real power and reactive power. Apparent power, denoted by S , is the magnitude of complex power. It uses the unit volt-amperes (VA) rather than watts. Power factor, abbreviated PF, will be discussed shortly. The following diagram is referred to as the power triangle. Figure 3. WebMar 17, 2024 · The following formula tells you the complex power S, which is written in terms of the complex impedance Z. Complex power in terms of complex impedance. Note that resistive portions of a circuit always dissipate real power, as we’ll see momentarily, while reactive portions only receive reactive power. Physically, the reactive power …
