The damage caused by electric shock depends on the current flowing through the body. 1mA can be salf, 5 mA is painful. A person loses muscle control, and > 70 ml can be fatal. The amount of damage done by the electric shock depends not only on the magnitude of the current, but it also on which portion of the body that the electric current is flowing through. The reason for this is that different parts of the body have different resistance, which can load to an increase in current.
