What is an electric shock?

In the Electrical Engineering field,many cases of accident or death around the world causes by electric shocked.It very dangerous because we cannot see,smell and feel the electric current.

Current flow into our body and can make heart stop from functioning and can cause the serious injury even death.The level of danger for electric shock depends on the value of the body current and the time for which the current flows.

Human body have a different insulation value (Ohm) and also different current value can effected the heart.For the body have a low current level,it can easily attack the heart function and it so dangerous.

How much current quantity to our body can stand?

To answer this question,we back to OHMS LAW of electrical resistance.In a case of a shock ,the amount of current through the body is determined by the following formula :-

I = V / R

I = Current

V = Voltage

R = Resistance of the body
