Yes, this is particularly difficult for the student. And the worst thing is, sometimes the instructor or publisher DOES make a mistake. But not very often.Woah, now it's looked more confusing. ahahahaha...
Okay now i'm agree with the term of the polarity change.
Thank you for the explanation sir.
The hardest part i think, when we (students), got a question and at the 'question' already defined the polarity of the inductor, and when we want to analyze it, and we should mark the polarity, my mind would be like, "Oh sh!t, my lecturer made a joke of us. If i marked polarity of the inductor like on the question, then i will have a wrong answer in reality. But if i followed the polarity as in the question, then i got the wrong anaylze of buck converter".
No one ever got 100 in the class then. ahahahaha
