​Effects of Electricity on Human Body

A person receives an electric shock when electric current passes through the body. Various factors such as the body's resistance, type and level of the current flowing through the body, the duration for which the current flows through the body, and the path it takes to flow through the body, determine the type and severity of injury inflicted on the body.

A person exposed to electric current may experience tingling sensations or a small shock for current levels of 1-9 mA (milliamperes), muscle contraction and burns for current levels up to 25 mA.  For higher current levels, severe injuries such as respiratory paralysis, ventricular fibrillation, and even death may occur.
