"But since we were talking about batteries, which are simple direct-current devices, power factor doesn't enter into it."

Ah - but that would only be for a steady state current - at the instant of making and breaking the contact, the current is changing, thus the natural (though very low) capacitance, and inductance of the human body will affect the calculation...







See - I can BS with the best of them... truly a little knowledge is a dangerous thing in the hands of a fool...
