How the intensity and duration of the current influence on electrocution

The electric injury represents a frequent risk of modern society, linked to the increasing use and continuous exposure to electric current . Within the thermal insults, they represent a small percentage, but their importance lies in the specific pathogenic aspects. Then the influence of the intensity of the electric current in the electrocution will be developed .

one

The degree of injury is directly proportional to the voltage of the electric current.

two

Injury is defined by low voltage when the voltage is less than 1000 volts, and injury of high voltage if it exceeds that value.

3

The low voltage injury is caused by contact with domestic current and that caused by high voltage exposure to sources of more than 1000 volts, as occurs in power plants or public lighting cables.

4

According to Ohms law, the intensity of the current is directly proportional to the voltage and inversely proportional to the resistance.

5

Since resistance is a difficult parameter to measure, voltage becomes the only known variable during the assessment of the degree of injury.

6

All injury by high voltage current must be interpreted, in principle, as the major producer of tissue damage.

7

This must be so, although in appearance the surface injury looks innocent.

8

In these cases the deep insult is usually not visible and is greater than the external one produced by the entry and exit points of the current.

9

With regard to duration, the greater the time of exposure, the greater tissue damage.

• If there is an electrocution, consult a doctor, the injuries may be internal and superficially evident.
• When trying to help an electrocuted person, the first step is to take them away from the source of energy by taking the necessary precautions so that it does not affect you as well.
