There are contradictions in the explanations of processes in grounding systems. In the grounding systems the current enters into the earth. What happened is that at the depth of a few meters it is impossible to find out any traces of this current. Where has it got to? There are many attempts to explain these processes. And all these explanations are different. Some people write that the earth is a huge capacitor. But, first, the capacitor should have the second plate. And, secondly, inside of the capacitor should be dielectric. And the earth cannot be a dielectric. The others explain the processes in grounding as current absorption. But absorption cannot be infinite. Any sponge, when it will be filled with water, will stop it to absorb. There are also other explanations, but all of them cause new questions.
