【電験二種二次】ケーブルの充電電流(2)(易：平成14年電力・管理問3)本番で書くならどのレベル？

Even if you can't solve it the first time, once you understand that you just need to define Ir, all you have to do is simply substitute values, so I think you'll be able to solve it without any difficulty from the second time onwards. However, because it's so easy to solve from the second time onwards, you may overlook the fact that your inability to define Ir the first time was due to your inability to grasp the situation. This is a rather complex problem that likely screened out a considerable number of test takers on the day of the exam, and even subsequent test takers have likely not grasped its fundamental aspects. Even if you can already solve it, make sure you have a basic understanding of the following two points: 1) Why is the voltage at the receiving end 154kV? 2) What are the currents flowing through the load and the sending current? Even if you're a liberal arts student who's not good at math or physics, you can get through Level 2! I'll leave the standard explanations to other videos and introduce more digestible problem explanations and study tips.
