When lightning generates high voltage, it will be transmitted to the user's electrical appliances along with the conductor of the wires, and at this time, if the electrical appliances are in use, the high voltage generated by the lightning will break through the electrical equipment. There are two types of lightning that can cause harm: one is ordinary lightning and the other is falling lightning. Ordinary lightning has almost no effect on electrical equipment. There are 2 kinds of hazards to computers caused by falling mines:

1, through the conductor directly burned with high current, this possibility is very small, can not be counted, a few millionths.

2, lightning produces powerful electromagnetic waves, causing hard disk damage to the computer, this possibility is also very small, but can not be ignored.

The voltage of the powerful thunder will lead to semiconductor integrated circuits are instantly pierced, lost the original polarity, so the integrated circuits are damaged, the computer is composed of a large number of integrated circuits, so the computer is also bad. There is also Ray's high voltage, instantaneous high-voltage discharge will lead to nitrogen in the air is punctured and burned, is to release a lot of heat, but also the computer will be burned to break the circuit, and then, the type of lightning belongs to the electrostatic force, understand the circuit know, electrostatic electricity is the integrated circuit of the first big killer, the computer is not a small harm.

Thunder has the opportunity to make the wires produce instantaneous high pressure, then high pressure may break through the electrical components, serious explosion may be triggered, minor will also burn the fuse. So if the thunder is more serious areas, sometimes even the lights must be turned off, because it may be suddenly open, injuring the near people, of course, if the clouds out of the thunder is very high, then there is no effect. Generally those who sound more scary thunder, the clouds are lower, this time it is strongly recommended to turn off, otherwise the probability of being struck by lightning is relatively large, and the equipment is damaged by lightning is devastating, take it to repair to replace the bad parts, the price is more expensive.
