What should I do if I have electricity on my body? People often refer to static electricity

Summary. Bathing and changing clothes frequently can effectively eliminate the static electricity accumulated on the surface of the human body. In people's daily life, sometimes due to clothing, climate, friction and other reasons, often cause the body to accumulate static electricity, and when suddenly touching metal, it will incur the pain of electric shock, and it can even cause some psychological pressure when it often occurs at a certain stage.

Frequent bathing and frequent change of clothes can effectively eliminate the static electricity accumulated on the surface of the human body. In people's daily life, sometimes due to clothing, climate, friction and other reasons, often cause the body to accumulate static electricity, and when suddenly touching the metal, it will incur the pain of electric shock, and at a certain stage, it often happens that even hail can cause some psychological pressure. If Gen Kyung-slip temporarily avoids touching the iron tool, the charge on his body may accumulate more, and sooner or later he will receive a greater electric shock.

Here are two tips to help prevent this shock. 1. In the house, static electricity may be generated after the carpet rubs against the sole of the shoe, and it may also be electrified due to the wind outside the house. At this time, be careful when entering and exiting the iron door, as your hands may be beaten by electricity.

After encountering this situation repeatedly, you can take the following measures to avoid electric shock: When touching the iron door, do not directly touch the iron door with your hands, but first grasp a large area of keys in your pocket with your hands (usually this will not be shocked), and then, use the tip of a key to touch the iron door, so that the electricity on the body will be discharged and will not be shocked. Principle:

The pain of the discharge of the hand is due to the high-voltage discharge, and the sudden contact between the hand and the iron door during the discharge is a very small area, so the instantaneous high voltage is generated. If you take out the key in your pocket, first hold the key in a large area (a bunch of keys themselves can't transfer much charge so there will be no electric shock at this time), and then use the tip of a key to contact a large conductor, at this time, the contact point of the discharge is not a point on the hand**, but the tip of the key, so the hand will not feel pain (maybe the key will!). --If it hurts).

2. Electric shock often occurs when getting out of taxis. This is mainly due to the accumulation of static electricity caused by the friction between the body and the seat when getting off the bus, and when the door is closed after getting off, the hand suddenly touches the iron door and is subject to electric shock. When this happens often, it's best to pay attention to:

When getting off the car, that is, when the body rubs against the seat, the metal door frame is held in advance, so that when the friction produces static electricity, the static electricity on the body can be discharged at any time, and the electric discharge will not be discharged when the hand suddenly touches the iron door after getting off the car.

Static electricity is mainly contact static electricity, that is, when an uncharged object touches an object with static electricity, the charge moves from a high potential to a low potential, like water flowing to a low potential, so the uncharged object generates electricity.

Dry indoor is often a high-risk area of "electric charges", due to the low humidity of the air, chemical fiber clothing, carpets, cushions, wallpaper, etc. are rubbed, which will produce static electricity.

If you touch live water pipes, electrical appliances, metal doorknobs, TV screens, and even switches with your hands, you will feel like being "electrified", and you will feel numb and painful. If the static electricity accumulates to a certain voltage, the phenomenon of "electric shock" will occur when people come into contact with it. Although the voltage of static electricity is large, the resistance of the human body is also very large, and its current is small, and the energy it has is small, so it will not endanger human life.

The principle is that the static electricity generated on the body is discharged through the path of the conductor of the wall, and the wall becomes an electrified conductor.

Static electricity on the human body is mainly caused by friction between clothing or clothing and the body, and touching the wall is because the wall can be buried and conducts static electricity into the wall (the main reason is that the wall is not an insulator). However, many walls are not very effective because they are tiled and painted, and the best way is to touch the best of the water pipes.

Static electricity is generated because the nucleus does not attract enough electrons to the outer shell, so it loses electrons under the action of friction or other factors, so that the friction is negatively charged (that is, the negative charge that gains electrons and the positive charge that loses electrons).

In the case of good insulation properties of friction, these charges cannot be lost and will accumulate. In addition, the capacitance of the insulator is extremely poor, resulting in a situation where the charge is not large but the voltage is very high.

Static electricity attached to the human body caused by the friction of clothing, etc. on the human body. Static electricity is generated because the nucleus is not attractive enough to the outer electrons, so that the electrons are lost under the action of friction or other factors, so that the friction has a negative charge.

Clothing made of chemical fibres is more likely to generate static electricity, while cotton clothing produces less electricity. And because the dry environment is more conducive to the transfer and accumulation of electric charge, people will feel that the static electricity on their bodies is greater in winter.

Under different humidity conditions, the electrostatic potential generated by human activity is different. In the dry season, the static electricity of the human body can reach thousands of volts or even tens of thousands of volts. When the electrostatic voltage is 50,000 volts, there is no discomfort in the human body, and there is no danger to life when the electrostatic voltage is 120,000 volts.

Electrostatic discharge also creates an electromagnetic field around it, which is of great intensity, although it lasts for a short period of time.
