what happens when an electric current passes through the human body ? why the person strongly shocked by electric current got dead ? is it due to some internal changes (like body temperature)?
skinny psyche is right the electricity interupts the nervous system that runs on electricity - and everything stops including the heart and breathing. It depends on how much and what type of electricity.
Below 1 Milliampere Generally not perceptible
1 Milliampere Faint Tingle
5 Milliampere Slight shock felt. Not painful but disturbing. Average individual can
let go. Strong involuntary reactions can lead to other injuries.
6 to 25 Milliampere (women) Painful shocks. Loss of muscle control.
9 to 30 Milliampere (men) The freezing current or “let go” range. If extensor muscles are
excited by shock, the person may be thrown away from the power
source. Individuals cannot let go. Strong involuntary reactions can
lead to other injuries.
50 to 150 Milliamperes Extreme pain, respiratory arrest, severe muscle reactions. Death is
1.0 to 4.3 Amperes Rhythmic pumping action of the heart ceases. Muscular contraction
and nerve damage occur; death is likely.
10 Amperes Cardiac arrest, severe burns, death is probable

Some people might think that the engineering involved in the creation of the human body is quite basic and primitive. Well, I must ask: Has anyone ever created a biologically functioning human body from scratch? Because...
