Wow! You just introduced a magnetic model that makes perfect sense _even_ given the limitations you describe here. I’ve been doing electronics repair at the component level for many years, now. So, your presentation puts into words what has been just beyond reach for me. Excellent video! I’m looking forward to part 2!

Actually the magnetic field energy is the kinetic energy of the moving electric charge,

[@philoso377]

We learn everything about electric and magnetic except one thing, we haven’t teach in what condition that E and B field’s existence are possible and what not?

[@gyrateful]

OK, Right.

[@rahulkumar-ny7hv]

Which book should be referred to practice the questions ?

[@rafalklepinski7372]

The text for this course is Principles of Power Electronics, 2nd edition. It was a very reasonable $70 CAD for an 875 page hardcover text. Compared to most university texts which cost as much as Taylor Swift tickets, this is a bargain.

@@rafalklepinski7372 Electrical Technology by B.L. Theraja. A very nice book with lots of examples

[@karimullahsarkar1592]

I have the pdf version, if you want the book drop your email address I will share

Principles of Power Electronics
This book is also super famous for German students,the university gives EPUB version for us for online reading

His handwriting on the board resembles the chaos of an impending apocalypse.

Hopefully there is not an apocalypse after an elementary school student sees the video
