Why do we get SHOCK if we touch current?

In summary, when current passes through a resistance, the body gets shocked. The current is not the kill, it's the current that kills.

why do we get SHOCK if we touch current??

when current pass through our body we get feeling of shock., why it happen?? person may turn black or die if exposed to high volt shock for long time?? why it hapens?:rolleyes:

Current through a resistance converts electrical energy to heat. The human body is mostly a resistance to current so it heats up. It's not supposed to be heated like that especially with high voltage or high current, so the body literally cooks like food on a hot plate but it does this internally. You are cooked from the inside like food. Like food, you sometimes burn and char.

your nerves are an electro-chemical system that work on fractions of a volt.

mild amounts of electricity passing through them gives that "tingle"
a little more hurts because it stimulates them harder

1/50 of an amp through the area of your heart can make it stop.

One thing important to note, it is not the voltage that kill, it's the current that kill. You can kill someone with a 9 volt battery. If you have both of you feet in two separate bucket of salt water and you connect two electrodes connected to a 9 volt battery one into each bucket of water, you'll be in deep dodo! Only take 10 to 20mA or so to fry a person.

The reason if you touch higher voltage, you only get a slight shock, is because the top skin is dead and dry and not conducting any electricity. If you dip in electrolyte and get into the porous, you get good connection into the blood which has salt and you complete the circuit. If you don't believe me, lick the two terminals with your tongue! I test 9 volt battery with this method, if it hurts, the battery is good!

if you've ever been in a small motorboat in the ocean, with everything covered with salt spray,

you'll find you cannot hold on to even the 12 volt battery terminal.
Salt water makes your skin so conductive that an ordinary car battery gives a painful shock.

So make sure your battery terminals are good and tight before you leave the dock.
It can be very difficult to tighten a loose one out there.
 

Question 1: What is electric shock?

Electric shock is the sensation that occurs when a person comes into contact with an electrical current. It is caused by electricity passing through the body, which can disrupt the normal functioning of the body's nervous system and muscles.

Question 2: Why do we get shocked when we touch current?

When we touch an electrical current, the electricity travels through our bodies and can interfere with the functioning of our nerves and muscles. This can cause a shock sensation, ranging from a mild tingling feeling to a more intense and potentially dangerous shock. The severity of the shock depends on factors such as the amount of current, the duration of contact, and the path of the current through the body.

Question 3: What are the dangers of electric shock?

Electric shock can have a range of negative effects on the body, from minor discomfort to serious injury or even death. In addition to the initial shock sensation, electric shock can cause burns, muscle contractions, and disruption of the heart rhythm. It can also lead to secondary injuries, such as falling or being thrown from the source of the shock.

Question 4: How can we prevent electric shock?

To prevent electric shock, it is important to be aware of potential sources of electricity and take precautions when working with or near them. This may include wearing protective gear, using insulated tools, and following proper safety procedures. It is also important to regularly inspect and maintain electrical equipment to prevent any potential hazards.

Question 5: What should I do if someone gets shocked?

If someone gets shocked, it is important to act quickly to minimize the potential harm. The first step is to safely disconnect the person from the source of the shock, if possible. Then, call for emergency medical assistance. While waiting for help to arrive, you can perform basic first aid, such as checking for breathing and administering CPR if necessary.
