There is a reason why 50V (AC @50Hz) is considered the safety threshold for humans. For DC, it is 120V.
quote: No, you're incorrectly using Ohm's Law. In simple terms, you must realize that real-world voltages are not idealized sources, and do not remain constant regardless of load. Even in the case of 120VAC house current-- once current begins flowing, the potential drops. Voltage is measured assumming infinite resistance (or, if you prefer, zero amperage).
quote: In the case I described, I most certainly was touching a >100kV voltage source while well-grounded, and thus current was flowing through me. A few microamps at most...which explains why I'm here typing. The reason your calculation of current was incorrect is, because the moment I touched that source, the current flow caused a corresponding potential decrease.
quote: Certainly; I never said otherwise. However the fact remains that amperage is the primary factor in inducing fibrillation. Voltage is irrelevant, insofar as enough exists to overcome body resistance.
