>>10947987There needs to be 10ma of current across the heart to kill you. This is why tazers have killed people: when your heart is in the past of least resistance between the prongs, a current will flow through it and, and you could die.
>>10946934Car batteries are not dangerous to skin. That is just movie nonsense. 12v is not enough to send enough current through the skin. If you put them on your tongue it might blow up, as you can feel the electricity flowing if you ever put the terminals of a 9v battery on your tongue.
In conclusion: a higher voltage is required to get current through the skin. In fact, once the voltage is high enough to get past the outer skin, your muscles are mostly water with loads of ions in them and conduct very well. If this voltage is not reached, electricity has no potential to be harmful. Past that, the current does matter.
