In real life, many natural scenes are caused by water flowing through rocks. So if we think about it, water can flow through hard rocks, not to mention other things.
?We can think about why water droplets penetrate stones. When water droplets fall, they will follow a downward process in the air and will be affected by many forces in the air, such as surface tension. and water molecules. The force of attraction, air resistance, etc. will form an air ball under the water droplet. The air in this space will be accelerated by the gravity of the water droplet and will wrap around the water droplet, forming a high-. pressure bubble.
When water drops fall on something, the water droplets and the surface of the stone also form a temporary closed space. When the high pressure water bubble burstsate, it will have a strong impact on the surface of the stone. This power is no less powerful than other Solid Impacts of the same mass.If a stone is subjected to such an intense impact over a long period of time, it is not surprising that it would be penetrated. It is worth mentioning that the higher the water droplets fall, the greater the impact. Because there is resistance in the air, water droplets falling from high altitude disintegrate when they reach a certain speed.
We also know that the atmosphere contains a lot of carbon dioxide and that carbon dioxide is easily soluble in water. When carbon dioxide is dissolved in water, carbonic acid is generated. This shows that water droplets in the air contain a. certain amount of carbonic acid, which has a weak acid. In addition, with the development of various industries, raindrops contain dans the nature of carbon dioxide. When carbon dioxide and rainwater meet, the acid rain formed is very corrosive and causes some damage to the environment. Therefore, if water must flow through something, as long as it flows continuously for a long time and the direction of the water droplets must remain consistent, then the water droplets can penetrate the object. This phenomenon also tells everyone that you must persevere in everything you do. As long as you are patient, attentive and find the right way to do something, you will definitely succeed.Earth in electrical engineering does not refer to earth in the literal sense of the term. It should refer to relative potential, not to a concept. And the earth is not a distinct substance.
Water being a conductor, it will of course cause an electric shock.
The stoneThe dryer is also close to the insulator and will not cause electric shock.
No, dry concrete floors are also insulating, but wet floors can cause electric shock hazards.
Theoretically, if the insulation resistance of the insulation is large enough, when a person stands on the insulation and touches the live wire with one hand, since the resistance is infinite, the current flowing through the human body is zero, that is, the current cannot pass through the circuit of the human body, old friends will not be electrocuted.
However, electric shock situations vary greatly and modes of electric shock are all kinds of strange. Most of them are not simple situations mentioned above, but often unexpected situations. For example, your hands are. relatively damp, or the insulation of the insulation is unreliable due to moisture, holesand other reasons cause insulation to decrease; When you touch the live wire with one hand, other parts of your body inadvertently touch the grounded wire. Objects and other situations can cause electrocution accidents.
Please do not try this situation.
The important thing to remember is that water exists in many places, and where it is involved it is easy to damage the insulation.
