Mobile phone fuse? Is it really dangerous to use a mobile phone when it thunders?

Do not know when the beginning, the rumors began to circulate such a saying: Don't hit the phone on a rainy day, or the end of the same as the outfit force is the same. Is there a scientific basis for such a statement?

From primary school, we have been exposed to a lot of this kind of text and natural knowledge, the more famous is Franklin Rainy Day challenge himself to fly kites and parents from the small "rainy days don't hide under the trees under the rain". So what are the factors that are affected by lightning on a rainy day?

In fact, from a scientific point of view to explain the phenomenon of lightning is very easy, that is, smaller resistance means more easily electrocuted. Taking shelter under the tree as an example, the distance from the surface of the cloud is considered to be proportional to the distance of the air. The top, roof, and body surface of the wet tree, the resistance is much smaller than the air in the rain, and because trees are much taller than humans, the thickness of the air layer between the bottom of the cloud and the top of the tree is much smaller than the thickness of the air layer between him and the body, so the resistance from the bottom of the cloud to the top of the tree As the number of electrons increases enough to enter the Earth through the top of the tree, lightning strikes occur at the top of the tree.

And so on, as long as people and clouds between the air resistance than a smaller media connection, the probability of people being electrocuted will be greatly improved.

Therefore, for our daily use of smartphones, the increase in lightning probability is almost non-existent. The size of the phone is too small for the impact of resistance changes are negligible. The famous American "gossip Terminator" program was designed to test lightning strikes. The experimental data clearly shows that "a mobile phone in the rainy day" does not increase the probability of lightning strike.

The appearance of this impression is mainly related to our daily habit of acquiring information. When the media reported that someone in the rainy days because of the use of mobile phones and the news of lightning strikes, our subconscious will automatically "use the phone on the rainy day" and "lightning" is equated. But completely did not think "how many people did not use the mobile phone when thunder, but was struck by lightning" and "How many people use mobile phone when thunder, but not by lightning hit" such a problem.

When you do a similar survey, you will find that the ratio of "use of mobile phones" to "hit by lightning" is only a small percentage of the population.

Although the rain Angel with mobile phone will not increase the probability of being struck by lightning, but need to remind everyone is that in the thunderstorm, the use of fixed-line telephone is very dangerous. This is because the phone line connects the outside with the interior, and outdoor objects are more likely to be hit than indoors. If the telecommunications equipment or surrounding objects are struck by lightning, it is true that the users of the telephone may be compromised.
