I believe the 'a' SHOULD be left out, for euphony. I see no reason,
except pedantry, to slavishly preserve the whole prefix when it results
in the vowel combination 'ao'.

http://en.wikipedia.org/wiki/Ohm

They even leave the extra 'o' in 'kiloohm'. That's silly. I've never
heard anyone say "kilo-ohm".

Cheers!

We will have to ask IEC TC25 for an official ruling. Expect the answer
later this century. Much later.

Kibis, anyone?

Isn't that dog food?

Thanks,

Like I was saying above, I think I can scrounge up enough 3 or 4kV caps
to put several in series, and get the capacitance down to 10pF or so.
These are usually tested to twice their rated value, so if two 3kVs are
in series, they should be able to handle over 10kV, not that they would
ever have to, tho.

What? You want to miss out on the fun of making your own glass HV
cap? Lessee - say your window glass is 1/8" thick, then from

C = 0.224 * (K * S * (N-1)) / d , where
C = pf
K = 7.5 for glass
S = area, sq. in
N = # plates
d = spacing, .125 for this example
(ref: http://www.kilowattclassroom.com/Archive/CapXC.pdf )

so, lessee... start with 2 plates, 1 sq.in. ...
C = 0.224 *(7.5 * 1 * 1) / .125 = 13.44 pf per sq. in. of plate. If you
use the foil from a gum wrapper, having peeled it off the wax paper,
you could probably stick it to the glass by just warming it up.

Have Fun!

I believe the authoritative source for this info in the U.S. is NIST,
which is in agreement with the rest of the world. Go here, and after
brushing up on the prefixes (and while there, brush up on the prefixes
for binary multiples, last paragraph), go to Rules and Style
Conventions.

Just like you, Rich! A baling wire and bubble gum solution!

Thanks for the reference. I may do that. Soon as I can find a piece of
broken glass and get it about the right size and thickness, without
stabbing myself with it. :-/

How did they, centuries ago, get the foil and stuff to stick to the
inside and outside of those Leyden jars? :-?

Egg white.

Reminds me of that verrrry old tricky (verbal) question:
How do you spell 'JOKE'?
How do you spell 'POKE'?
How do you spell the white of an egg?
Many if not most people immediately say 'YOLK'!
and then find that they screwed up when they're told it's spelled
'albumen'.

Some vandals threw raw eggs at the wall of a neighbor's house on
Halloween, and after it dried it was very difficult to get off. Someone
once told me that they used to use it as the binder in paint.

I'm wondering how egg white can dry when it's covered up with aluminum
foil. Maybe it doesn't need to.

You must have had a "dead" one then. I have had some that pack quite
a bite. They do wear out as the pile accumulates fractures.

The good electrostatic igniters like like used for lighting gas flames are
operated by a lever mechanism and can pack quite a punch, the cheap ones
in disposable lighters work with a sort of spring-loaded pile-driver
and often the plastic parts of the mechanism fail. and the shock of the
hammer hitting the piezo element isn't real good for that part either.

barbecue igniters are much more powerful than the disposable lighter ones too

I've read that the secret to his violin making was in the shellac he
made. But I don't know about the glue. Horsehide glue, I would
imagine.

A ham I once knew put up cupboards in his garage with wood glue, and
years later (when he moved out) when he took them down, in some places
the wood separated not on the glue line, but pulled out chunks of
splinters. So the bond can be very strong if the joint is thin.

Yeah, here's a URL that verifies that it's hide glue.

Did you see the show on HBO about "The Ice Man"?

That dude is cold.

Nope, didn't see it.

I'm just an asshole. :-]

If you say so. I have always felt that honesty is the best policy.

Well, keeping in mind that it was probably tin foil, they probably
just formed it to the surface and it just stays where it's put, at
least on the inside.

On the outside, of course, they used duct tape. ;-P

Everyone knows, Rich, that in France and thereabouts, they don't make
tape out of ducks, they _eat_ ducks. ;-)

I'm not sure that Leyden in the Netherlands is 'France and thereabouts',
but considering the amount of water around there, duck-eating was
probably quite widely practised.

It's pretty popular in China (and Chinatowns worldwide) as well. Those
beautiful BBQ ducks hanging in the window along with BBQ pork,
cuttlefish and chickens. Pretty good in congee. And, of course, most
famous Beijing Duck.

Varnish or other paints seemed to be a popular adhesive in earl
electrical work

Artistsmade their own paints using egg whites..

Flour paste would do on the short term..

Unless the ducks ducked into the ducts.
