Each year in France, for example, 200 people die of **electrocution** and 500 suffer
serious injuries, often permanent burns, respiratory paralysis, cardiac arrest, 
etc.

The various level electric current have different effects on the human body. Here
we are discussing the effect of electric current at 50 Hz frequency :

Effect of Current on Human Body

 **0 – 0.5 mA **

Below the level of perception, usually resulting in **no reaction**. 

**0.5 mA – 5 mA **

There are no dangerous physiological effects, a [current](https://studyelectrical.com/2017/12/what-are-current-resistance-and-voltage.html)
of this order may state a person sufficiently to result in **secondary injury due
to falling, dropping items** etc. 

**5mA – 10mA **

produces the same effect as above but, in addition, the muscular reaction may cause
an **inability to let go of equipment**.

In general, the **female body is more susceptible** to the condition than the male.
Once current flow ceases, the victim can let go. 

**10mA – 40mA **

10mA – 40mA produces **severe pain and shock** are experienced as current increases.
Currents over 20 mA the victim may experience breathing difficulties with **asphyxia**
if current flow is uninterrupted.

Reversible disturbance to heart rhythm and even **cardiac arrests** are possible
at higher values of current and time. 

**40mA – 250mA **

produces **severe shock** and possibility of non-reversible disturbances to the 
normal cardiac cycle, referred to as “**ventricular fibrillation**“, occur at this
level.

The possibility of fibrillation increases as current and time increase. It is also
possible to experience **heavy burns or cardiac arrest** at higher currents.
