What is the physical cause of electric death and current killing?

1 The minimum current that the sensed current causes the human body to perceive. Perceived current generally does not cause any harm to the human body.

2 get rid of the current, the maximum current that can be rid of by itself after the electric shock. It is generally believed that the average current of the human body is 15 mA. Considering the safe current that does not have the risk of electric shock under various conditions, 5 mA is suitable.

3 The lethal current jeopardizes the minimum current of human life in a short period of time. When the current flowing through the human body reaches 50 mA or more, it will cause ventricular fibrillation, which is life-threatening; to 100 mA or more, it is enough to cause death in a very short time.
