Power Factor Angle Between Voltage And Current

Power Factor Angle Between Voltage And Current. This angle represents a phase displacement between voltage and current when pure sinusoidal (undistorted) waveforms exist. Power factor = cos ϕ.

Efficiency versus load current and Regulation versus power from www.researchgate.net

The cosine of the angle between voltage and current is considered (not sine or tangent or cotangent angle), because the phasor diagram of voltage or current from power triangle is. The ratio of the true to apparent power. For an ac circuit, 0≤pf≤1 whereas for dc circuit power factor is always 1.
