To those who say “its not the voltage that would kill you, its the current”
A 9 volt battery, like a car battery, does have the potential to output enough current to kill you easily. But why doesn’t it? It is because your body, and mouth, do not draw enough current to kill you. This is because current is equivalent to voltage, current = voltage / resistance. Say the amount of tongue in-between the anode and cathode of a 9v was 1800 ohms ( its probably somewhere near that). That would be 9v/1800=.005. Or 5 miliohms, within the range of pain but without killing you. Now lets do it with a 12v battery. 12V/1800= .006. That would feel almost exactly like licking a 9v battery. Yes a car battery can output hundreds of amps, but it wont. A 9v battery can output a couple hundred milliamps, more than enough to kill you. But why doesn’t a taser kill you? Well yes a taser can output huge amounts of voltage, but it wont because the current just isn’t there to begin with. Spread this info so that others will know and to treat real hazards like hazards
