Electric Shock is the flow of external electric current through human body, which is pathophysiological reaction.
Which causes Electrical injury on human body, like damage skin or damage of internal organs.
Pathophysiology (convergence of pathology with physiology ) is the study of disordered physiological processes due the injury.
Electrical injury is damage (physiological reaction) caused by electric current passing through the human body.
Symptoms are skin burns, damage to internal organs, damage to soft tissues, cardiac arrhythmias, respiratory arrest.
Touch Voltage is the voltage between the energized object and the feet of a person.
If there is Insulation failure in the Object, Object body will get energized, and if personel touches such object, due to higher resistance earth path of energized object and human body to ground compared Object to ground, there will the Touch Voltage.
Indirect Contact, is the contact with outer conductive part of Object, like metal Body of the Object.
Normally Metal Body of the Object should be properly eartheed, and hence it will be dead. But if there is any internal insulation failure in the Object, the Object’s metal body can become live.
Upon touching such live object metal body parts, it will cause electric current to pass through human body, the current would depend on Touch voltage and human body resistance.
