Well, it takes voltage to make current, right? I always think of the
human body as a 10kOhm 2W resistor. But if the current is directed
arm-to-arm across the chest (i.e. through the heart) even a small
current can cause big trouble. A small shock applied at a
particularly inauspicious time in the heart's electrical cycle can
cause a deadly rhythm disturbance.
