What harm does lightning do to people, and what are the dangers of lightning to the human body?

Thunder is lightning again, divided into sound and electricity, sound is not very harmful, but it is easy to make people sleepless at night. Electric currents are generally not dangerous to people because they are not easy to access, but do not take shelter from the rain in places that are prone to lightning. If you are struck by lightning, you will suffer burns all over your body.

It's almost a one-hit killing. Only a handful of people survived.

Lightning strikes can injure or kill people.

It's going to electrocute people. The voltage that the human body can withstand is less than or equal to 6V, and can the voltage as high as lightning withstand it?

There are many types of mines, torpedoes, mines, and what people often call thunderbolts. It's really inappropriate for the questioner to ask such a question, and I hope to change it! A good question can be answered!!

Trouble, thanks!

Thunder is an atmospheric phenomenon.

Thunder is caused by the friction of positive and negative charges between clouds and clouds in the atmosphere to produce violent discharge, produce high temperatures, make the atmosphere expand sharply, and produce a deafening loud sound, which is lightning and thunder.

When atmospheric charges are constantly accumulating in the clouds. If the amount of charge becomes strong enough, lightning will occur. When lightning crosses the sky, it can quickly warm up the air along its path.

The heated air expanded rapidly and slammed into all directions as violently as it had happened. This creates a huge sound wave, which we sound like thunder.

The most common lightning is linear thunder, the most dangerous to guess the charge of the great judgment, sometimes you can also see the sheet thunder, and there will also be ** spherical thunder spikes. In the discharge area, the current can reach hundreds of kiloamperes and the voltage can reach millions of volts, and the destructive force is very huge, such as touching trees or houses, it will be knocked down, and touching people and animals will be electrocuted or scorched, causing disasters.

Lightning Protection Advice:1Try to avoid thunderstorms. If you find a thunderstorm in the area, immediately go to the inside of the building to take shelter from the lightning, or run to a high place away from the minefield;

2.Stop outdoor activities, immediately enter the building or take other measures to evacuate;

3.Do not stand in exposed places such as forests, rooftops of buildings, open-door cars, boats, etc., and do not stand in open areas;

4.When lightning protection outdoors, try to keep a certain distance to avoid damage caused by current shuttle;

5.Use metal objects to prevent the spread of electric current, and try not to use wooden or other non-metallic objects;

6.Remember, thunderstorms and thunderstorms are usually accompanied by strong tropical humid air, so don't sit on grass or rooftops when it's not raining;

7.In a climate with high temperature and high humidity, thunder accumulation may occur, so it is necessary to prevent short circuits of electricity in the scenic area;

8.If you find that there are high-voltage lines in the scenic spot, you should avoid outdoor activities such as setting up tents in such places; Lack of rent.

9.If you find that you have been struck by lightning, you should leave the scene immediately to avoid a second strike.

What are the injuries to the human body caused by lightning disturbances? （）

a.Direct action of electric current (correct answer).

b.Overpressure or kinetic action (correct answer).

c.High Slow Hood Thermocracking Effect (Correct Answer).

There are three main hazards of lightning strikes: The first is direct lightning. It refers to the strong discharge of a thundercloud to a certain point on the earth.

It can directly hit the equipment, or as shown in Figure 1, lightning strikes overhead lines, such as power lines, ** lines, etc. Lightning currents then enter the equipment along the wires, causing damage. The second is induction mines.

It can be divided into electrostatic induction and electromagnetic induction. Electrostatic induction can be found in Figure 1. When a charged thundercloud (generally negatively charged) appears above a wire, a large number of opposite charges are bound to the wire due to electrostatic induction.

Once the thundercloud discharges to a target, the negative charge on the thundercloud disappears instantly, and a large number of positive charges on the wire still exist, and in the form of lightning waves, the wire passes through the equipment to the ground, causing damage to the equipment. Electromagnetic induction can be referred to Figure 2. When the lightning current flows into the earth along the conductor, due to the high frequency and high intensity, a strong alternating electromagnetic field is generated near the conductor, and if the equipment is in this field, it will induce a very high voltage, resulting in damage.

This is especially the case with sensitive electronic devices. The third is the increase in ground potential. When a lightning current of 10 kA enters the ground through the lower conductor, we assume that the ground resistance is 10 ohms, and according to Ohm's law, we know that the voltage at the entry point A is 100kV.

Because point A is connected to points B, C, and D, the voltage of these points is 100kV. The E point is grounded, and its voltage value is 0, and there is a voltage difference of 100kV between the D point and the E point of the equipment, which is enough to damage the equipment. Note:

According to statistics, only 15% of the damage is caused by direct lightning, and 85% of the damage is caused by the increase of induced lightning and ground potential.

The energy released by a single lightning strike can make a city last a day, and it is not a problem for people scorched by lightning to be instantly scorched (above 2000 degrees).
