About :
We present to your attention the first issue of a series of lectures on electrical safety, dedicated to the basics of electrical engineering. Professionals will understand... But even if your work is in no way related to electric power engineering, and you just want to refresh your memory of the school curriculum, we highly recommend watching our material. 00:00:00 Intro 00:00:17 Lesson questions 00:02:45 Electrical engineering 00:03:01 Electron theory of the structure of matter 00:06:35 Coulomb's law 00:07:38 Potential.
