How many volts can kill a person?

there is no such fixed voltage, as people struck by lightning have also survived

By the electrician hand book the danger current flow is a small window of 100 to 200 Mil amps. any thing less than 100 u may hurt yourself,and above 200 ma. u will receive burns. In the window above it starts the heart to flutter.

Not exactly spontaneaous but In case of certain baterial infection there has occurred that the temperature of the boddy got way  over 107 degree F and the person died really burning up.

depends on the voltage

What kills you is not the voltage but the amperes. Current (amps) = Voltage / Resistance. This is ohms law. 10mAmps causes muscular spasms. 30mAmps causes respiratory failure. 75 causes ventricular fibrilation that is the ineffective pumping of the heart. Until this point, the heart can gain back its normal rythym if a defilibrator is used. beyond 4amps, the heart stops functioning and beyond 5 amps, tissue in the body starts to burn.

Current burns, voltage jerks the muscles.  Too much current, you're toast.  Too much voltage, your heart stops.\n\nStatic built up from rubbing your socks on the carpet probably won't kill you.\n\nSeveral years back, in the wintertime, there were some news reports of people whose car blew up at the gas pumps.  Supposedly it was due to static electricity.\n\nIt's rare to get "shocked" outside when getting in or out of one's car or touching it or whatever but it does happen.  I remember a couple times in the past 5 years when it happened to me. A tiny percentage of times I have done that but way more than zero.\n\nSo, I guess the combination of a spark and being by your open gas tank could kills you, indirectly.\n\nTaking an extreme counter-example, there was a girl struck by lightening at the WHFS alternative rock festival in DC a few years ago. Apparently it knocked her a few feet from where she was standing.  But, it didn't kill her.  She was lucky.\n\nStatic charges build up more easily in wintertime. The air is dryer.  Something about the air molecules is different when there is less moisture.  I forget what, but you have probably noticed more "static" shocks in winter than any other time of year, unless you live in a really cold, dry place.\n\nA three inch spark seems pretty far.\n\nIn high school physics class, they said that each inch that a spark travelled off a sphere through the air indicated 10,000 volts.  I think it was 10,000.  Well, you're not a sphere and you are probably not touching one but that still seems like a lot.\n\nI used to get shocks of half or three quarters of an inch  when touching the corners of walls at the house I grew up in all the time.  That was really nothing.  I barely felt it.  It was just a surprise to feel it, and also to see the spark leap between the wall and your finger.\n\nModern buildings have grounding wires on all the outlets and stuff like that, to prevent electrical problems.  Not sure what really old buildings are like.\n\nIf you are wearing a sweater or wool clothing, that could increase the amount of static charge you build up.  There are all kinds of things that could do it.\n\nIf it happens on warm, humid days when you are not wearing any wool or sweaters, that would really be strange.  If not, maybe it is what you are wearing or the atmosphere that is mostly responsible.\n\nAlso, carpet is a big factor.\n\nFeeling it hours later, that's freaky. That never happened to me.

lead, poisonous gas emmissions...you are talking about damage...this stuff can kill you

The current in a lightning bolt is as high as 30,000 Amperes with 1,000,000 or more Volts. The short duration of about 1-100 milliseconds limits, but doesn’t prevent injury. There are several mechanisms of lightning injury. The most severe is a direct strike, either on the victim or on some object the victim is holding such as a golf club, tripod or umbrella. A “side flash” occurs when lightning hits a nearby object and jumps to the victim. Ground current injures the victim when lightning strikes the ground nearby and it spreads to the person. Rarely, people maybe injured or killed indoors while using the telephone or taking a shower.

personally I wouldn't worry about anything under 50 Watts\n\nmore than that, limit usage or get distance from whatever it is\n\nliving under high voltage power lines is way worse and they have a hard time proving what that does, I know its bad for people though, how bad and in what ways I don't know

Have a look here: http://en.wikipedia.org/wiki/Cathode_ray_tube Scroll down to the Health Danger section.

The internal circuits of most stun-guns are fairly simple, either based on an oscillator, resonant circuit and step-up transformer or diode-capacitor voltage multipliers to achieve the continuous, direct or alternating high-voltage discharge may be powered by one or more 9 V battery depending on manufacturer, and model.  The recipient of the tazer shock (poor fellow) is actually imobilized as two metal probes touch the skin and send a high-voltage current through his or her body, causing great pain and temporary paralysis.

Well depends on the max load the circuit can handle. If the circuit can sustain a max load of lets say 10 volts and you push 15 to it, the circuit elements will heat up and fry. Of those elements will include inductors, transformers (up and down) logic controllers, resistors, transistors, capacitors, motors, and a multitude of other components. Lets say computer for example, you would fry the CPU and possibly damage all the attached components! Either way it's a bad situation.\n\nJust increasing the the resistance values of the resistors will not prevent damage. The designing of circuit boards isn't a fly by night type of thing. In some cases you can get seriously hurt or waste alot of money so exercise caution. Good luck.

they are deadly if you suspect you have one get help ASAP. i had one after my son was born and was given 50/50 chance to survive. thank god i did but DO NOT MESS AROUND with this!!! please!!!

It is DC voltage.\n\nhttp://www.ecs.umass.edu/ece/allerton/papers1999/36/

According to wikipedia, the lethal dose of nicotine for a person is in the range of 40-60mg.\n\nAccording to Philip Morris, Marlboro Full Flavor 100s Filter cigarettes deliver about 1.1mg of nicotine each.\n\nSo, you would need to smoke enough cigarettes to have the nicotine content of about 40 cigarettes in your body at the same time, in order to experience a "same day" death.\n\nOf course, there are the following factors which may move this number up or down:\n1) Different brands and types of cigarette, as well as different styles of smoking (eg. how long you hold the smoke in your lungs, whether you cover the filter holes with your fingers) will deliver different amounts of nicotine.\n2) Different people metabolize or eliminate nicotine at different rates.\n3) Different people will have varying tolerance to vulnerability to the immediate effects of nicotine.  For example, if you have a pre-existing health condition, it will make it easier for the cigarettes to kill you.\n4) Cigarettes and other tobacco products contain many other toxins, in addition to nicotine.

I used to work for a wire company and it sometimes ran the wire through a part of the machine called the Hi Pot test it would run 10,000 volts through the wire and if it burned through the insulation than the machine would stop and you would cut the defected wire away and retired the machine but I would get shocked every time the hi-pot machine would kick off.  It made my mussels contract abit and made me jump.  Some times when I didn't have money for coffee I would stick my finger in the hipot to get a zap to wake up. It hurt a little but it woke me up just the same.  Any how it isn't the Volts that kill you it is the Amps.  The Higher the Amps the greater the current is.  Like you could get killed with only 12 volts if the amps are high.  consider Water the smaller the hole the faster the water goes because of pressure.  Well Amps are like that.  The Higher the Amp the greater the pressure.

Here's an idea. Make one that will shock people(low voltage) when they ring your bell. ;-)
