Radio and （details） |
| First, the kind of lightning and thunder and lightning hazards there are two kinds of direct lightning strikes and thunder induction. Thundercloud between live and direct lightning strikes is caused by the earth discharge. When the charged thunder clouds low around opposite charges and no clouds, it will be induced on the ground or in a building opposite charges, when the potential difference is large to a certain extent, to the ground or the air breakdown ... |
