    My question about the lightning rod

    There is a lightning rod on the house. But is it safe to use? Lightning can cause damage to, for example, a tree, destroying it completely. It's not stupid to attract lightning to a house with a lightning rod. In addition, the power of the lightning is so great that it is unlikely to be...
