Explain the working principle and process of lightning rod

Ans:

The principle of lightning rod is not to block the lightning but to protect the building from lightning by neutralizing the charge in the cloud with the charge on the ground along a safe path. The bottom of the cloud is negatively charged, so the induced positive charge collects on the ground under the cloud. According to the principle of electrostatics, the more pointed place on the surface of the charged conductor, the electric harshness density will be higher than other places, so the tip of the lightning rod will be more than other places *** with more positive charge, guide the negative charge in the clouds along the lightning rod frequently to the ground discharge, so as to avoid the accumulation of negative charge in the clouds too much, one over discharge when the formation of a huge destructive power of the lightning, hitting the ground to gather a large number of positively-charged Buildings. So, what is the relationship between laser and lightning rod? It turns out that the right laser can ionize the air, creating a conductive channel composed of positive charges, negative caustics will obediently go along this channel, to the near ground, it will be in the pre-prepared traditional lightning rod discharge. This method can be more effective in inducing clouds of electric caustic discharge through the lightning rod, thus greatly improving the efficiency of the traditional lightning rod. Physicists are now investigating the use of ultraviolet lasers to discharge two electrodes; they have used high-voltage electrodes to simulate the generation of lightning and have successfully discharged two electrodes at a distance from each other with a laser. In the future, "laser lightning rods" could be installed at airports, hospitals, and nuclear power plants to protect people
