From the consumers POV it means that more power is being consumed to get the

Of course, there aren't a lot of loads that are purely reactive.
Of course not. Everything has wiring so there is always _some_ resistive loss. But a motor WORKS by induction!
Also, for many years, fluorescent tubes used inductors for ballast, which introduced significant power factor.
That's 'balancing' factor. The tubes by themselves represent a capacitive load at low frequencies. At the higher kilohertz frequencies that Tesla operated the, that's another matter. There's a long and ugly history of why we have such a low frequency for power distribution. Be glad its not 15Hz or lower! -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
