Is it just the amps that will kill you?
There is a lot more to electrocution but this is a start. For one, different forms of electricity may or may not induce ventricular fibrillation in the heart, which is where you drop and hope someone starts CPR as another runs for an Automatic External Defibrillator or AED. BTW, defibrillation is usually 200-360 joules or watt seconds of dc countershock.
If you survive, you may still go into renal failure 3-5 days later as the myoglobin in your blood clogs your kidneys. Ever noticed that brown jelly-like stuff when you fry a bloody steak? That's what your myoglobin looks like in your bloodstream after an electrical shock.

When he was talking about the resistors in tasers for saftey purposes i wandered if somthing similar is put into spark ignitors? Because i felt the bite of one on an oil burner around 10Kv. Not to pleasent but im none the worse for wear.

That was a great tutorial video. Thanks for sharing. BTW, where it says "finger under here, dead" well that isn't necessarily true. I put my finger there once when I was a kid. Didn't keep it there long. It didn't kill me but in retrospect it explains a lot.

Another smart ass liberal video. If someone has something important to say they shouldn't be a dick about it, it removes any creditably they may have.

I used to work in a TV repair shop years ago - under that rubber cap on the CRT is called the second anode. On a color TV it ran around 24kv, but was inherently limited to a couple milliamps of current. I too have gotten tangled up in one and it is no fun.
Not mentioned so far is that whether or not you are electrocuted (killed) has a lot to do with the path the current takes through the body - through the heart and vital organs or not, as well as the amount of time you are exposed.
It's also true that many deaths from electricity are not the result of electrocution but secondary injuries (falling off the roof/ladder, jerking into the path of machinery, etc.).
Be safe out there!

I say the amps kill you, the volts give it reach. In other words, the higher the volts the further from it you need to be to stay safe.
Fwiw, an arc blast can be hotter than the sun, and copper expands 65,000 times when it vaporizes in the arc.

This is a topic for tourists.

Actually, that video frame shown on the embedded youtube vid with the arrow pointing to the anode is not labeled correctly.
I took 29,000 from a cathode ray tube anode driver circuit in 1995.
Reports of my death are highly exaggerated.
I can tell you this: it WAS painful.
Now, had the conditions been correct, I COULD HAVE assumed room temperature.
But, I generally take precautions to keep that from happening.

Volts are the EMF that facilitates current flow. Thank you for an informative video which, as a person with a minor in electrical engineering, served as a reminder.
I've got a really important question to ask you hearthman. About a year and a half ago there was post on this site about a boiler explosion in either Kentucky or Tennessee that occurred at a small factory. I think either you or timebuilder posted it, do you remember where and what?
I've got a presentation to make and would love to find this. My searches on here and google have been fruitless.
Also, as well, if you guys are interested in the effects of current I urge you to research and study Thevinins Equivalent and Superposition Theory and the related algebra needed to describe it.
Thanks again for posting something extremely relevant.
RobertThe picture in my avatar is of the Houston Ship Channel and was taken from my backyard. I like to sit outside and slap mosquitos while watching countless supertankers, barges and cargo ships of every shape and size carry all sorts of deadly toxins to and fro. It's really beautiful at times.....just don't eat the three eyed fish....

I will try and find that for you tonight.
