ARPPPF =Power Factor (PF) Daya Nyata (True power) merupakan fungsi dari Risistansi (R) dalam sebuah rangkaian. Daya Tampak (Apparent power) merupakan fungsi total Impedansi (Z)dalam sebuah rangkaian. Oleh karena itu, faktor daya merupakan perbandingan rangkaian resistensi dengan rangkaian Impedance ZRPF = selesai Power Factor (PF) Membandingkan Impedance segitiga dengan segitiga daya Compare the impedance triangle to the power triangle. R and PR are both the side adjacent to angle u. Z and PA are both the hypotenuse of the triangle. The phase angle of a series reactive circuit can be found by the cosine of the angle formed by the adjacent side and hypotenuse.Therefore: u = cos PFInductor Quality Factor (Q) An inductor has resistance due to the fact that it is simply a piece of wire.All wire has resistance. This resistance (RW) results in some true power being consumed by the inductor. Even in a purely inductive circuit, RW is present and subtracts for the total energy that can be stored in the field. Inductor Quality Factor (Q) This resistance appears to be in series with the inductor. Generally speaking, it is very small and can be ignored, but in some applications it must be considered. Quality Factor (Q) The quality factor (Q) of a coil is a ratio of the energy stored in the field (due to XL) to the energy dissipated in the coil by the resistance (due to RW). Q is a figure of merit and has no unit of measurement.
