Human Body Capacitance and Resistance

And that is through the side of the chest and the chestplate bone.

It takes far less in an open heart surgical procedure.

Let me point out that I was thinking of a component postmortem.

JEDEC standard JESD22-A114D spells out the familiar HBM ESD test model: 100pF in series with 1500 ohms.

Fisher's Severe HBM was created from hundreds of measurements reported in the literature. His interest was in the worst-case observations. His 360-ohm value of body resistance is lower than you observe with simple ohm-meter measurements, etc., but keep in mind it's a high-voltage measurement. Is it reasonable to hope that our outer-skin-layer insulation can withstand a say 20kV discharge and maintain high-resistance?

Well, since people regularly charge themselves up to at least 30kV (a 1 cm spark) I would say not.

Right you are. As I clarified earlier, I was thinking of a component postmortem.

Except that he was referring to the chip. D'oh!

In the usual case of people charging themselves up by shuffling their shoes on carpet, they make sparks in gaps with uneven electric field. So, less than 30 KV can make a 1 cm spark. If one end of the spark gap is a sharp point or the tip of a wire maybe AWG 22 (approx. .63 mm) or smaller, then a 1 cm spark can occur from about 11 KV, easily from 12KV.

Also, these sparks often appear bigger than they are. I find 1 cm to be uncommon, but I find 8 mm fairly easy to achieve with favorable shoes and a fairly favorable carpet and favorable humidity. So, I think 10 KV is common but much more is not.

However, I remember experiencing one apartment with one exceptionally favorable carpet and I somewhat remember making 15 mm, possibly 18 mm sparks (corresponding to probably about 17 to possibly 20 KV).

If you had read my hole post you would have seen that I mentioned that right after quote above. See below

Quote: "Don't you understand Ohms Law, if resistance goes up (dry skin), current goes down, YOU IDIOT!. Also it take the same amount of current through the body (dry skin, moist skin or open wounds) to cause their heart to fibrillate. The closer you are to the heart the less current it takes because more of that current will flow directly though the heart.

Resistance goes down for open wounds(assuming the current goes into the open wound) because there is a direct connection to the internal fluids of the body, hence less voltage is needed to cause fibrillation. With dry skin (high resistance) it takes more voltage to cause dangerous amounts of current to flow.

I never lost in the first place, but you always lose!

You must have taken that paragraph right out of a book, bravo! I know you don't have the brains to come up with that your self or even put together a paragraph like that.

No it's not. You talked about all sorts of variations.

The problem with your hole post is that it was as wholly insignificant as this last post of your was.

Yet more proof of your total retardation. The fact is, and it is obvious... that you do not "know" a goddamned thing about a goddamned thing.

Voltage causes current to flow. If the resistance is high, it takes more voltage to pass a dangerous level of current through the body. If the resistance is low, it takes less voltage to pass a dangerous level of current through the body. I agree current causes fibrillation. Again you never read my hole post. LEARN to read Dimbulb!

You lose!

The energy level of a defibrillator is measured in JOULES, a joule is watt*seconds. A defibrillator (monophasic) starts at 1 joule and goes up to 360 joules on most machines. In newer style defibs they are biphasic and less energy is required to defibrillate a heart, they usually max out around

"hole post", ALwaysWrong?

Obviously not.

Defibs run around 60 amps peak with pulse widths of a few milliseconds. You are wrong by a factor of about 30,000:1, about average for you.

You shouldn't ever state numbers. You are AlwaysWrong.

I don't think that's the issue. It's a brainless attempt to cover all bases with the fewest tests. 'Betting' would make just as much sense.

Rationally, you'd have to examine the effect of the range of conditions, to see what actually had the most serious impact on varying targets. There could, for example be a joule-second effect, rather than simple breakover 'pinholes', that high voltages, greased by local moisture, couldn't produce.

Being able to anticipate committee-think and to suggest it right off the bat, however, is the sign of a real up and comer.

More like a 'Post Hole'

It takes two total retards to see (or miss as is your case) that I was correcting the mistake of the idiot.

More proof that the Williams bitch is getting more senile as each day passes.

Read HIS post, you pissy little bitch.

My post is a proper, humorous correction post.

Your post is retarded baby bullshit.
