From the consumers POV it means that more power is being consumed to get the
same amount of work done. When the voltage and current are completely out of phase no useful work is being done even though the power is being transmitted. More current, no more power. When the phase shift is 90° the power is zero.
Of course, there aren't a lot of loads that are purely reactive. Also, for many years, fluorescent tubes used inductors for ballast, which introduced significant power factor. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
