ЧИ ТРЕБА ВСЕ ВИМИКАТИ КОЛИ ГРОЗА? | ЩО ТАКЕ ФАЗА ТА НУЛЬ?

Together with Yasna, we have prepared a series of interesting issues where we will analyze issues related to electricity and explain it all on our fingers. In the thread, I asked people to write questions about electricity in everyday life that concern them, to consider them and explain them in simple words. I did not expect that there would be so many of them, so we will make several issues. We chose a few of them for this issue.
