It's actually a combination as you need a hazardous voltage in order to be able to persuade the current to flow. You can't kill someone with 3V batteries, even if you put 10,000 of them in parallel. Believe me, I've tried. |

Touching your tongue to something like that, has got to leave a nasty taste in your mouth. Heck of a way to attempt suicide....

Well, sure. I always think of voltage as the width of the electric "pipe" you're using. You need ph4t p1p3z in order to have a decent enough current. But yeah, 50k volts is nothing without the current behind it. |

Current is not something that exists apart from voltage and resistance. It is dependant upon the two. If I put 10,000 3V batteries in parallel they could deliver 10,000 times the maximum current rating of one 3V battery but only through a very low resistance. The higher the resistance the lower the current. The internal resistance of the human body is not very high but you have to pass the current through skin as well which has a very high resistance. Hence the need for 10,000 volts and the reason why the current is still very low (apart from the fact that it is very likely limited within the device itself in case a "good" connection with the internal body is somehow achieved). |

So if i put 10 3v batteries in parallel across a 5 ohm resistor the voltage across the resistor is still 3v? What is the difference then between having 10 in parralel and just having 1? If the volatage is the same then for a given resistance surely the current will be the same and if the current and resistance is the same then the power is going the same, etc. etc. Also what i if i put them in series rather than in parallel? |

If you put one 3V battery or ten 3V batteries in parallel across a 5 ohm load you will get 0.6 amps either way. You will just be able to get it for ten times longer with the ten batteries. If you put ten 3V batteries in series you will get 30V. Putting that across a 5 ohm load you will get 6 amps. |

Ah ok so infact you can kill someone with 10,000 3v batteries - you just need to put them in series rather than in parrallel. 3v batteries ftw. Cheers for the clarification. |

Unfortunately, the internal resistance of a typical 3V battery is fairly high and putting 10,000 of them in series would severely limit the current. In fact, the internal resistance of a battery or any electrical power source is a sort of measure of its current delivering capability. |

Damnit, now i'll have to find another method of execution. Actually it would interesting to see what the maximum voltage one could apply to a given resistor using however many 3v batteries in series would be. Any guesses? |

A resistor is rated by power handling capability. since power is voltage times current then a 5W resistor would, well, you can work that out for yourself I'm sure. |
