Watching TV in thunderstorm weather

Because lightning will generate high-voltage electricity when it thunders, it will be transmitted to the user's electrical appliances in the form of upside down wires. At this time, if the electrical appliance is in use, the high voltage generated by lightning will break through the electrical equipment.

There are two kinds of mines that cause injuries: 1 ordinary mines and two-layer mines.

Don't worry about ordinary thunder, it only shows off in the sky.

There are two kinds of harm caused by floor lightning to computers.

1

The possibility of large current burning directly through the conductor is very small and negligible, one in a million.

2

Lightning will produce powerful electromagnetic waves and destroy the hard disk of the computer. This possibility is also very small, but it cannot be ignored. If you like computers, you'd better turn them off.

Television:

Watching TV when it thunders, the picture is very unstable and the interference is great. I always feel a little scared, worried that the plane will crash and people will die. Is this possible?

In fact, as long as you don't connect the outdoor antenna and use the TV indoors, there is generally no need to panic, because although the lightning is fierce, before entering the room, the thunderstorm cloud has already discharged with the earth. In the process of short-time discharge, most of its huge energy is converted into heat, light and other energy, so it will not cause harm.

Usually, when it thunders, I watch TV in my room. Most of the interference on the screen and in the sound is the radiation energy of lightning, not the energy of induction or discharge. This radiant energy generally won't damage the TV set.

However, it must be emphasized that it is very dangerous to use outdoor antennas or watch TV when it thunders. If you watch it, you must take lightning protection measures.

Electric light:

When it thunders, the voltage suddenly becomes very large, which will cause the lights to go out and cause a fire. However, there is usually no need to turn off the lights. Because the voltage is getting bigger, the work of the substation is suspended, that is to say, there is a power outage, so the lights at home will automatically turn off even if they are not turned off, which is very safe.

Computer:

Strong lightning voltage will cause the semiconductor integrated circuit to be instantly broken down and lose its original polarity. Therefore, the integrated circuit will be damaged. A computer is composed of a large number of integrated circuits. When the integrated circuit is broken, the computer is broken.

In addition, the voltage of lightning is very high. Instantaneous high-voltage discharge will decompose and burn nitrogen in the air, release a lot of heat and burn the computer.

Moreover, the type of lightning belongs to static electricity, and everyone who knows the circuit knows that static electricity is the first killer of integrated circuits.

Lightning has the opportunity to generate instantaneous high voltage on wires. At this time, high voltage may break through electrical components, leading to serious explosion and even slight burn of the safety tube. Therefore, if it is in an area with severe thunder, sometimes even the lights have to be turned off, because it may suddenly explode and hurt people nearby. Of course, if the thunderstorm cloud is high, it has no effect. Generally, the thunder that sounds scary is low clouds, so be sure to turn it off at this time!
