- Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA).
- The triangle that is created when adding the resistance to the reactance is known as an impedance triangle
- The power factor has also been defined as the ratio between resistance and impedance
Hence the power factor is Cos ϕ = \(R \over Z\)
