Spam overwriting text and text overwriting test.

Horrible.

Plus you have not quoted the basic definition of Power Factor.

Do YOU even know it ???

This need a lot of work.

If the reader knew enough to understand the first equation, they
wouldn't need the article. You do not define imaginary current, nor
power factor (in a general, conversational) way before you launch into
math. The math should quantify what is first understood,
conceptually. Your approach also does not include harmonic power
factor, but only phase shift power factor (without hinting that it is
covering only one of two possibilities).

Do you need a consultant?

We?

It's still crap.

_You_ keep pretending that you're an authority of some kind, but you
still don't seem to really know the difference between reactance and
resistance.

8. ### John PopelishGuest

I still think you need to start with a question (the opening
"question" is just a phrase) and say what displacement power factor
is. The current drawn by a reactive load has two components. One is
power consumed by the load (or converted to some of the form of power,
like mechanical). The second component represents energy that is
stored by the reactance and then returned to the power source, twice
per cycle. So the line current represents power passing one way, from
source to load, and also energy sloshing back and forth between source
and load as short term loans. The combination of both energy flows
produces relative a phase shift between the line voltage and line
current.

If the reactance is inductive, the energy is borrowed mostly after the
voltage peaks so the current peaks lag the voltage peaks. If the
reactance is capacitive, the energy is borrowed mostly on the way up
to the peaks, so the current peaks lead the voltage peaks.

Then the math shows the details of these processes.

The first line (in red) isn't a question, as JP points out.

I think your page is aimed at beginners, and therefore you should avoid
the exponential notation; stick to simple SIN(wt+theta) notation.

Regarding the reference you give at the bottom; what is PAQ 93? If you
want your readers to actually find this reference you must give more
description.

Finally, you would do well to find somebody whose native tongue is

I'm not seeing that.

12. ### Pooh BearGuest

Probably browser dependent which indicates the page code needs sorting.

13. ### VeyGuest

That's what I figure. But I'm not willing to break my browser to sort it.
IE6 and TB1.5 these days that's about all I worry about. The others are
in the >5% range.

14. ### Phil AllisonGuest

"Vey"

** Then you are not using IE with Windows XP set to larger fonts.

The overwriting problem is rare and generally only seen on sites created by
amateurs.

........ Phil

15. ### VeyGuest

That's exactly right Phil, I'm not. You fit into the >5% classification,
then.

16. ### VeyGuest

But don't feel bad, Phil. You have good company. The Mac users with OS7
are right in there with you. They also claim that "only amateurism"
creates pages they can't see properly.

Yes, pages can be created so that you see them properly. Too bad they
are designed for IE4 & NS3.

** What a shame you cannot afford a decent PC.

** You have the arrow the wrong way - fuckwit

XP & IE dominate the PC world.

"Vey"

** This IS one very slimy piece of asinine wog shit for sure.

** "Vey" fits right into the classification of a demented scumbag.

** Now the slimy pile of wog shit has resorted fabricating false quotes.

Here is a real one.

" The overwriting problem is rare and generally only seen on sites created
by
amateurs. "

** Now the slimy pile of wog shit fabricates a completely false scenario.

Sure has a monstrous axe to grind over something.

Tiny cock syndrome - I bet.

19. ### VeyGuest

Thanks Phil.
I needed that.
I'll be sure to tell anyone here to plonk you.

"Vey"

** This wog asshole very clearly psychotic.

B E W A R E !!
