【電験三種】平成30年度 理論 問8【交流回路:ベクトル図の使い方】

I'm making videos that focus on quickly solving problems for the Electrical Engineering Examination. Today's topic is "2018 Theory Question 8." The problem asks you to find the phase difference between the voltage applied to an inductive load and the power supply voltage using given information. The key is whether you can correctly draw a vector diagram. I'm using vector diagrams to explain the problem, but in the second half of the video I'll explain how to solve it using equations and the relationship between typical power factors and angles. I hope you find it useful.
