It can also be calculated from the power triangle. Formula of Power Factor: The power factor formulas are listed below: If we know the value of angle of lead or lag i.e. Since active power = VICosØ and apparent power = VI, it can be calculated by calculating the ratio of Active Power and Apparent Power. pf = CosØ. Ø then pf can be calculated using information (1). Where, · Cosθ. Therefore, · Cosθ = True Power/Apparent Power. Power Factor Formula For Single Phase · P =VI Cosθ. Rearranging the above formula we get · Cosθ =P/VI. For the purely inductive circuit, the power factor is zero, because true power equals zero. Power Factor Values For the purely resistive circuit, the power factor is 1 (perfect), because the reactive power equals zero. Here, the power triangle would look like a horizontal line, because the opposite (reactive power) side would have zero length. The power factor of an AC circuit is defined as the ratio of the real power (W) consumed by a circuit to the apparent power (VA) consumed by the same circuit.
