Would you care to give us a scenario? The best source I could find places the minimum resistance of already damaged human skin at 500 ohms. With 9v of potential

Would you care to give us a scenario? The best source I could find places the minimum resistance of already damaged human skin at 500 ohms. With 9v of potential, that translates to .018 amps of current, which is just barely above the threshold for sensation, let alone death.
- boomlinde 9y ago0.018 is way above the threshold of sensation, well into the territory of very painful shocks (18 times the threshold of sensation at ~1mA). Of course this will usually be local with a 9V battery, but with some deliberation you can pass the current through your heart via the blood stream, where the resistance is sometimes much lower which can get you very close to what'll likely be fatal. Edit: the above holds true for AC but not necessarily for DC from a battery, where the thresholds are typically higher. But the heart is very sensitive and fibrillation occurs at very low currents passing directly through it.
