Is there a lightning rod? Is it safe to thunder?
Buildings with lightning rods are safe during the thunderstorm season, and of course, you don't recommend using cell phones or showers in case of thunderstorms.
If the cloud charge too much, not even to neutralize the tip discharge, then there will be lightning, but don't worry, because the metal of lightning, the lightning will be near to lightning, and lightning itself has a connection to the earth from the roof of the wire can be a large amount of current to the earth, so as to avoid on the building of the damage
The principle of lightning rod tip is to neutralize the charge discharge, the clouds above the floor, so that the lightning discharge heated into tip discharge smoothly, thus reducing the probability of occurrence of lightning near buildings
Although the lightning rod increases the safety factor of buildings and equipment, but the thunder is still a strong electromagnetic wave and current, mobile phone is very easy to be damaged in strong electromagnetic wave, current is generally through the lightning rod into the earth, occasionally may enter through the water inflow pipe, so in case, as far as possible not to take a bath
