What happens to our body if touch live wire of 240 V ?

Explanation

240 V current disturb the functioning of organs inside the body. It is called electric shock. If the current flow continues Further, it damages the tissues of the body which leads to decrease in resistance of the body. When this current flows for a longer time, damage to the tissues increases and thereby the resistance of human body decreases further. Hence, the current through the human body will increases. If this current reaches 0.07 A, it effects the functioning of the heart and if this much current passes through the heart for more than one second it could be fatal.
If this current flows for a longer time, the person in electric will be killed.
