Re: Hey do you know your car's alternator only outputs 7-10% while it'srunning?

Transients are exactly that.

What the hell are you talking about.

Transient defintion http://en.wiktionary.org/wiki/transient

A transient phenomenon, especially an electric current; a very brief
surge.

excursions defintion http://en.wiktionary.org/wiki/excursion

A brief recreational trip; a journey out of the usual way

So you would consider modulated waveforms (digital/ data/audio) as
transients. Thats a pretty unique interpetation. Wow I could have made
my testing much simpler when asked to identify modulation tequniques
all I had to say is it's a transient.

Do you even know the difference between a periodic wave an a
non-periodic wave?

The answer was in response to this : And, like the series Xmas lights
of yore, when one goes out, they all go out.


YES, ditz, and THAT very remark was made in reference to our discussion
about carbon arc lamps in series!

And my response to that remark was ALSO about carbon arc lamps in
series, and anyone that actually lived back then knows it.

Have a look at this image:

Just above the bead of glass that stabilizes the electrodes/filament
supports you will see a few turns of silver wire wrapped around the
supports. This is the wire that causes the bulb to fail shorted. Under
normal operation only the bulb's nominal operating voltage is present
(2.5V-12V AC depending on the number of bulbs in the string) which is not
enough to burn through the oxide layer. Once the filament breaks the full
line/mains voltage is suddenly put across the bulb and the oxide layer is
penetrated causing the silver wire to short to the supports which makes the
bulb unit itself a short circuit. The result is that the rest of the bulbs
in the string stay on and get slightly brighter because of the slightly
increased voltage across each of them. The raised voltage also shortens the
life of the rest so they end up burning out in a cascade effect until either
A: they all burn out and short which blows the 3 amp fuse in the plug, or B:
the set gets jarred or shaken which knocks loose some of the shorts which
then don't reshort because the line voltage is distributed across all of the
opens and is not high enough across any given one to cause the bulb to
reshort.

Both outcomes result in a dead string of lights so it is best to change a
burned out bulb as quickly as possible to extend the life of the set.

You are talking Brockie Pel style arclamps from the late 1800s - I
know they were common particularly on the right side of the pond into
the 1900s. They were 50 volt units run 10 or 12 in a string on 500 or
600 volt DC circuits.

And if a carbon arc lamp did not light it also was designed to "fail
shorted"

Not ALSO, you ditz. THAT is what I was referring to, and NO, they do
NOT fail shorted, also or otherwise, by design.

The one I had had a fixed rod positioner, and if the lamp extinguished,
they did not spring together!

Why do you bring up this irrelevent drive,l?

It is entirely relevant to your previous post. That's why I posted it.
I know if I posted asinine drivel like you I would probably be eager
to forget it too. But here I'll paste it here for you to jar your
feeble brain.

Ring any bells? The first sentence shows your ignorance.This is
entirely dependent on the capacitor type as well as the application it
is applied to.Depending on the ripple current 0.1 ohm may not be
negligible let alone 5.

You know there are some people who can be arrogant about a subject
I've met a very few ,but you sure aren't one of them. You should
follow some simple advice if you don't know what your talking about
STFU.At the very least dont come off like an arrogant obnoxious ass.

Well the Brockie Pel's which WERE series connected DID fail shorted.
In the Brockie Pell system that is the way they worked, and I was only
speeking of the Brockie Pell - which was used in Bristol among other
places.

Also the quite common Thomson-Houston system had an auxiliary solenoid
directly across the arc, slamming the electrodes together if the arc
was estinguished and also provided continuity to the current loop.

NO! You said "and like the Xmas lights..." which means that you were
talking about arc lamps in series. THAT is what my comment is about.
No, I said, "like the Xmas lights of yore," i.e., about fifty years ago.
(which I also wrote quite clearly.)

Ergo, I took you at your word from your response to it.

So go take your nap, and quit being so bitchy.

Thanks,

The discussion went on about arc lamps in series. THEN, YOU made the
above remark, as in:

"Just like the ARC LAMPS..."

When you said "like the xmas lights of yore."

SO, MY response was CLEARLY about ARC LAMPS.

ANY DITZ that came along and read it the wrong way has a fucking
problem.

It has nothing to do with sleep OR bitchyness ... on MY end.

It has been a long time since i have read such crazy irresponsible
trash. I have worked a few projects that were a conversion from
series lighting (6.6 A, 4800 V) to 240 V systems. Worker safety was a
part of the issue. The odd thing is that at each lighting standard
there was a transformer, to make the normal voltage for the
lamp/ballast. The cost of the transformers seems to have added to
impetus of the conversion.

YMMV

The discussion was about ARC LAMPS. There are no fucking ballasts.

Try reading the thread next time.

You are an absolutely clueless idiot.
ALL vapour lamps - murcury, sodium, or whatever are ARC lamps - and
they all use ballasts.
The common FLOURESCENT lamp is an ARC lamp - and it too requires a
ballast. Virtually all arc lamps with the exception of the open carbon
arc lamps REQUIRE ballasts - and even some carbon arc lamps, when run
on AC, used ballasts.

OK you fucking ditz. The discussion was about open element CARBON ROD
ARC LAMPS.

NOT FUCKING GLASS ENCAPSULATED modern day jobs!

Want to match 'dumb' in a refereed, timed, session? Your choice of place,
my choice of subject matter? Or the standard SAT will suffice. I haven't
taken the SAT since 1968 so it should be a fair judge of 'dumb'. I let my
'68 score stand, you take the SAT.


I'll let my '78 score stand.

**** you.

Archimedes' Lever

BTW. Have you found your fulcrum? Without the fulcrum a lever is utterly
useless. Much like you.

Learn that stupidity in 68 as well?

Dumbass. A lever is the entire device. It includes the fulcrum.
Otherwise it is just a stick. Like you... a stick in the mud.
You are a fool-crumb.
