Electrocution of the Human Body

Physiological effects of current density on the human body are shown in the table below. Contrary to popular belief, it is the current - not the voltage - level which is responsible for effects. According to Ohm's Law, of course, a certain voltage is required to cause the necessary currents to flow. Values show vary depending on the body.

Personally, I have been hit with 480 V while working on a 3-phase industrial motor connection. It didn't feel good.
