The physical knowledge and mathematical foundation related to electrician are very few, even pitiful; Because there are many things in electricians, especially the automatic control of analog circuit equipment, how to reasonably carry out the series-parallel relationship of distribution, and learn to read the circuit diagram with a three-meter shaking table (megohm) clamp table (first look at the cross-sectional view and then look at the comprehensive general plan), and you will soon be competent. We don't need to analyze the design, but we can also analyze the distribution of current to voltage (R (resistance) C (capacitance)) in a segmented loop. The nature of L (inductance) and its series-parallel relationship, as well as an uncle and a master make you fly more comfortably. Don't worry, you will do well. At the same time, I still want to ask a proverb; Don't be careless about the electric tiger, and strictly follow the trajectory, especially the high-voltage and high-frequency parts. This is no small matter, because I have worked all my life and handled many accidents, and almost 100% of them are not operated according to the track, so-well, I wish you success after this! Work hard! ! Come on! ! ! If you don't understand this question, you can ask. If you are satisfied, remember to adopt it. If you have any other questions, please adopt this question and send it to me for help. Not easy to answer, please understand, thank you.
