We used to watch cartoons as kids, especially Tom and Jerry. Electric shock You may recall that situations like this are depicted as comical elements and they happen frequently. In this situation, which we see in many other cartoons, the skeleton of the character exposed to the current usually flashes from his body. that you shine we have seen.
In addition, in some cases, when exposed to electrical current, the characters may be meters or throw away or by the source of said current unable to break contact they were noticeable. So how are these two situations different from each other?
First of all, we should know that electric current is not foreign to our body.
The ability to raise your arm, speak, that you can thinkyour ability to eat and all your other functions, your nervous system with electric movements happens.
However, in cases that we know as electric shock, the current that arises comes in extra, and therefore, when it comes in contact with our body, stimulate muscles. But it has to be strong enough to pass through our skin and reach our muscles.
At this point, our body acts as a barrier to the electrical current.
This feature too dry and thick owed to it. Because when we get wet, we are more vulnerable to electrical current. This is important because the extent to which we are affected by the current is not in the middle. enter our body determines the current. Tension therefore plays a major role here. Here let’s summarize the information that the amount of volts sufficient to break the body’s resistance is 500 and above, and this value will be enough to stop your heart.
for example 50 milliamps If you have a cable in front of you, you will not directly experience this current, thanks to the resistance it gives when your body is dry. This is the stream it will be harmless It does not mean that, but it is necessary to know the difference between the visible and the experienced.
The electrical current entering your body wants to come from somewhere else.
Also for this the resistance is low seeks the way out by following the roads. Although the starting point is the feet, it should never be used in the treatment of such conditions. remember doesn’t move forward.
However, it should be noted that the current from low-power electrical sources will not penetrate the body, but will leave scars on the skin. Such movements are the subject of the content anyway.
Now let’s move on to our main topic. Let’s start with why we can’t leave the power source in some situations.
As we mentioned earlier, the thing that allows us to move our muscles is the electrical current. by myself. Now imagine holding an electrical source with both hands. This source gives you 10mA subject it to a flat stream.
This level of current, which hits your flexors, allows you to bend your fingers inward, allowing you to control your muscles. can occur and meanwhile a continuous, uncontrollable to contract can cause. For this reason, it may not be possible to leave the electricity supply.
Electric current for the same reason Lake will be exposed and irreversible damage may occur apart from the loss of muscle control.
So, is it possible to be launched because of an electric current?
Although this situation is exaggerated in cartoons, yes, possible. But electricity is only one stimulus does its job. Our own muscles do the main work.
Just now 10mA We have summarized the situation that a stream of . When the same situation occurs in different muscle groups, it has an effect In the opposite direction can show up.
That is, when your muscles are exposed to this level of current, they contract (much more strongly than normal). backwards can cause it to fly. Here, both the muscles that are stronger than normal and their contractions simultaneously reveal this result. In other words, which muscle group gets the upper hand over the other by being stimulated more determines which one will be experienced.
Let’s list the effects of milliampere values ​​so you can visualize them:
- only at 1mA level noticeable you feel an electric current at some level. However, that doesn’t mean it won’t be dangerous.
- If it is at 5mA level, it is we suddenly took There is little shock. However, this can lead to wounds with continuous contact.
- Between 6 and 16mA, the muscle control we mentioned in the content lost known as the area.
- In the range from here to 100mA level danger of death starting. Severe convulsions and injuries are also possible.
- If it is between 100 and 2000mA, the shock has been received to heart rhythm coincides with the levels at which it intervenes. Pretty deadly.
- 2000 mA and later, severe burns, cardiac arrest and organ damage seen level. Not to mention the degree of lethality.
