When we made hospital-quality defibrillators, they
put 400 Ws as a 3 kV pulse into 50 ohms load.

And yes, it leaves nasty 4 inch diameter burns,
despite of the contact lube used.

Are you sure you know what 30 PA is?

Oh, and incidently, one generates atleast a kilovolt under the 3kv
you claimed was necessary to jump a mm.

You are a goddamned retard. The number I gave is the accepted
number from the scientific community.

You have credible references for this? Share them please.

> I'll go with that over your layman ramblings any day.

Heh, well, as I said, I'm not generating 75kv in that ciruit, but
it's jumping over an inch, just fine.

That would be the microwave
oven transformer. It typically generates no more than 2 to 2.5kv.

The differ from maker to maker, and you are clueless about any
other than the one you toyed with. Unless you are a service tech,
and then I will start laughing all over again.

Do you have any experience with microwave oven repair? The majority
of ovens sold for retail use are being supplied with 2kv
transformers.

It
uses a voltage doubler to generate the 5kv dc necessary to run the
magnetron; but the transformer itself isn't making 5kv. [g]

Wow. you know fuck all next to nothing about microwave ovens
too.

Umm. I wasn't talking about inverter ovens, but the plain jane heavy
transformer models. They are using a voltage doubler to get 5kv to
feed the magnetron. The transformer is NOT generating 5kv DC to run
it on it's own. There's a big fat DIODE and a capacitor in the
circuit too; which is a voltage doubler!

So anyways, your statement is flatout wrong. Sorry.

Yeah, you are one sorry layman mother fucker.

Heh, well, my video clearly shows that your statement of needing 75kv
to make an inch long jump isn't accurate. Not even close. You're a
fucking electrical accident (a statistic) waiting to happen.

It's not just voltage, it's amperage. It's got kick behind it

You ain't real bright. If it builds enough to reach the ground
due to having the voltage to breach the gap, the ensuing
connection will have high current for the moment of the event.

Not necessarily. You can have whats known as a 'cold' arc, too. It
has very little current behind it, it's so weak infact it can't even
ignite fuel vapor. A battery powered bug zapper circuit, aka, a juul
thief can generate a tiny arc; it's not enough to bring you any
serious harm and won't even light a piece of paper if you tried.

> So, it is JUST THE VOLTAGE.

No, it isn't. How much experience do you actually have with HV?

However, modern tubs and the pipes connected to them are
plastic. Thus not grounded. Is it still possible to get
electrocuted in an ungrounded bathtub, if an appliance falls in
the water?

Errm, why do you want to know?...

Mike.


Just an appliance in the water is not going to make a path
through the body in either tub.


Uhh, I wouldn't bet my life on that by trying...

Uhh... You a basic electronics guy, eh?

I was reading this in home.repair. Didn't notice, until today it's
crossposted.. What is basic electronics to you?

Pure water is a
lousy conductor, but, most people's water has minerals in it;
which makes a pretty good conductor.

We do not need a primer on water conductivity in an electronics
newsgroup.

As I said, this isn't just in an electronics newsgroup...


> Pretty much common sense around here.

I've learned due to the electronics repair and electrical trades
based on experience not to assume people have common sense or
understand even the basic concepts...Sorry if you took my post as
something other than what it was intended to be.

The tub of water is NOT connected to "the water supply" once the
tub is filled. You have logic flaws in your argument.

It is if the tub happens to be a metal drain.. Doesn't matter if you
have very little water coming in contact with the top of your plugged
drain, you're still making contact. Common sense tells me, that not
everyone's homes plumbing is all plastic. Oh, it's that damn
electrical trade experience I have, wiring the fucking things...

If you're in the tub, you're in the way, part of the
circuit, not good to be you.

OK, so I thought you were a basic electronics guy, but you even
fail on that.

*yawn* Didn't checkout the channel available via the link I published
huh? The 1st video is a commercial wiring job.

Bullshit. A bread bag has the strength to withstand household

Plastic bags normally have microscopic holes in making them unsuitable as cap dielectrics or insulators. Caps require a better grade of film.

I have HV supplies at LANL and that went up on space shuttle

not even know what LANL is, much less anything about space bound
electronic packages. I know more about arcing than you do...
obviously.

Right. Nothing line voltage level is gonna breach. This is not
manufacturing grade. This is basic fact, and there are not any
microscopic holes in PVC pipes that are going to allow a breach
either. We are not making caps here. We are modeling tub safety and
or lack thereof and or lack for the need thereof.

The drain is not connected to the feed tap manifold.

So, NO, the water line is NOT connected to a tub full of water once
it is filled and the water is off.

You are 'an electrician', use an ohmmeter. You "wiring folks" know

The ones I looked only had one diode and capacitor. Seems to me to be a
1/2 wave rectifier. Hardly a voltage doubler.

Under a light load you may get 1.41 times the voltage of the secondary
of the transformer.

If it was a voltage doubler circuit which would require atleast 2 diodes
and capacitors you would get about 2.5 times the transformer voltage
under a light load.

the magnetron _is_ a rectifier. the diode and cap are to double the

As the diode conducts (tf top output +ve), the cap charges +ve left, -ve right.
As tf output goes -ve, the feed to the maggy is tf -ve voltage + cap -ve in series, so yep it's a v doubler. Like any v doubler you won't get as much as 2x out, but a lot more certainly.

Had those burns several times and the contacts were carefully placed

tell by the burn pattern how much energy was used (100J = outline of
contacts, 300J = full burn pattern). Was awake for one. ...remember
yelling something about the doctor's ancestry.

30mA, my ass, but what can you expect from AlwaysWrong.

A bath that's wet all over near the taps is thereby connected. And with all the splash as it fills, wet it will surely be.
