## Sily child...Stun gun?

I don't know who to be more disappointed at... the Police, for reacting as such, or the kid for being dumb enough to bring it to a public school.

Does anyone know who on instructables did this? lol

I do believe that there facts are wrong, it's a taser and it doesn't produce 600 volts (unless they had some monster of a camera). And they really aren't dangerous (unlesss you lick it)

While not exactly dangerous, they are stun guns, and they can easily produce 600 volts. It's current that makes it hurt, not voltage. For example, you can produce much, much more than 600 bolts just by rubbing your socks on the carpet and touching a door knob.

Quite the opposite actually. It's Voltage that "hurts"... it's Current that kills. A 20,000 Volt shock of static hurts/"zings"... but doesn't kill you.

A useful mnemonic device taught to Electrical Engineering students is "It's the Volts that Jolt, but the Mils that Kills." (speaking of Miliamps, a measure of Current.)

On the other hand, a low voltage-high current would probably kill you.
Estimates of between 0.7A to 1.0 A are the apparently the minimum to kill a person through electrocution. However, currents as low as 0.2 A would be enough to stop the heart, also causing death.

I believe the only caveat here would be that there must be enough Voltage to overcome the internal resistance of the human body. A VERY low voltage, even with high current may not have enough electro-motive force to actually create a grounding through the body.

Not the opposite, we were talking about how dangerous it is, therefore it would be obvious that "hurt you" is in reference to how much of a threat it is to one's physical well being. And as you confirmed, the current is just that.

you guys missed two key point here: 1) higher voltages are not only safer because they have less amps; the implication of screwing up with 10kv is much greater than screwing up at 110 volts. so a lot of people are careless with low voltages, compared to hv. 2) a lot of people survive the initial shock, only to die of heart failure several hours later.

what about 9v? doesnt that mean...(licks battery)

ahahahahah no, he has his facts wrong.

o, dang, i gotta go apolagise to my friend. i told him that 600v is safer then 300... i guess im just so gosh darn gullible.

hahahahah, but you can't measure deadlieness with just voltage. you need to know the amperage/current, nothing else matters. but in most cases, yeah, higher voltage is safer, but only if it's being converted... you may want to read up... hope this helps!
