WebPower Consumption. Now we will use all the above formulae to derive Power in AC circuit. We know that P=VI. So we can write power consumed in an AC circuit is: Note: Since P= V … In electrical engineering, the power factor of an AC power system is defined as the ratio of the real power absorbed by the load to the apparent power flowing in the circuit. Real power is the average of the instantaneous product of voltage and current and represents the capacity of the electricity for performing work. Apparent power is the product of RMS current and voltage. Due to energy stored in the load and returned to the source, or due to a non-linear load that distorts the wave s…
WebMay 17, 2024 · We know that power factor (pf) is an important parameter for calculation of power in an AC circuit. For a given power and voltage, the current flowing through the line is inversely proportional to the power factor. This means that a poor power factor i.e. low power factor will result in higher load current and hence higher losses. Web(R). Reactive power is a function of a circuit's reactance (X). Apparent power is a function of a circuit's total impedance (Z). It should be noted that power factor, like all ratio measurements, is a non-dimensional quantity. For the purely resistive circuit, the power factor is 1 and the power triangle would
