Significance of power factor in ac circuits
http://hyperphysics.phy-astr.gsu.edu/hbase/electric/powfac.html 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.
