Understanding Electricity Without Memorization

I will explain the contents of electrical circuits and control engineering from the basics. There is no need to memorize formulas. You will acquire the science habit of "understanding phenomena, expressing them in mathematical formulas, and finding solutions." I will explain things in a way that is easy to understand, so I would be happy if you feel like, "Oh, so that's what it means!" The current content of the explanation is "analysis of DC and AC electrical circuits" and "relearning the basic mathematics that is the foundation." In addition, the explanation will be expanded to "transient phenomena," "control engineering," "similarities between electrical systems and mechanical systems." 
   In parallel, I will also provide detailed explanations of typical examples, past questions from electrical engineering exams (mainly theory type 3 and type 2), and how to answer past questions from graduate school entrance exams.
