Equation for real power
WebA simple circuit contains the minimum amount of components that allow it to be a functional electric circuit: a voltage source ε ε (battery), a resistor R R, and a loop of wires for current I I to flow around (see Figure 6 below). We usually ignore any resistance from the wires. Figure 6. Simple circuit diagram.
Equation for real power

Web Cosθ = Power Factor kW = Real Power in Watts kVA = Apparent Power in Volt-Amperes or Watts WebS = V → ⋅ I → = P + j Q. where P, the real part of S, is the average power. The rms phasor voltage and current for the time domain voltage and current above are: V → = V m 2. I → = I m 2. The complex power is then: S = V m 2 I m 2 = V m ⋅ I m 2. Since, in this case, S is purely real, the average power is: P = V m ⋅ I m 2.
Webcould be used to calculate the real power by: P = 120 V x 6 A x 0.8 = 576 Watts Equation 4; Correct Calculation of Real Power Therefore, it is correct to calculate AC Watts by: P = V x A x PF = Watts Equation 5; Real Power The PF is used to compute real power. Real power is always expressed in Watts, while apparent power is expressed in VA.
