We all know that electric shock occurs when electric current flows through your body. electric shock merely startles you or it is fatal. Voltage itself may have wee to do with it. Voltage (V) is a measure of electrical possible and current (amperage) is a measure of electron flow rate. Knowing this now we can say, it's not the electrical possible (voltage) that affects you, it's the flow of electrons (current) through your body that does you wrong (electrocute).
Other factors that decree the extent of electric shock injury include. The number of Resistance your body gives to current that flow through your body. Secondly the path the current takes and finally the distance of time it travels. Citizen can have different resistance to current flow in there body but here is some general measure of effects of different current levels measured in amperes to your body.
Shock
Less than 1/2 milliamp no sensation
1/2 to 2 milliamps Threshold of perception
2 to 10 milliamps muscular contraction
5 to 25 milliamps painful shock (may not be able to let go)
Over 25 milliamps Could be violent muscular contraction
50 to 100 milliamps Ventricular fibrillation
over 100 paralysis of breathing.
You can see that there is a high occurrences of death around 25 milliamps up to about 100 when passed through the heart. We all understand why the low amperage will scrambles/confuses your neurons (electrical pathways) in your body that are transmitting information, thought, touch, motor control etc, this stop permissible body muscle contraction even to the heart(Ventricular fibrillation).But why if it is over a 100 milliamps does it not necessarily kill you?. Well it turns out, you tighten up so much, that your chest holds your heart still until the power is released. At that point your heart may undoubtedly restart -The down side is that the rest of you is not undoubtedly in good shape. May cause muscles tear up even bone breakages and boiling of the blood?
In fact higher the voltage the lower the current, but ordinarily higher voltage will carry more current when traveling through a path. If you find this inconceivable, then explain how Citizen survive lightning strikes and dead birds don't rain from the power lines.
