Is the direction of the voltage and current in the secondary just due to the way the wire has been wrapped around the transformer core as I have drawn in the picture attached?
In a flyback convertor, why does the polarity of v2 on the secondary winding change compared to a normal transformer circuit as shown in the picture attached?
If the voltage and current, v1 and I1 in the primary winding are flowing in the same direction in both circuits shouldn't the polarity...
Its ok, i found the explanation in a book on google books. Its a bit long and tedious.
I guess no one here would be able to understand it which is why i got no reply. Oh well...
Homework Statement
I've attached a page from the book Elements of Electromagnetics.
I was wondering how he gets from eq.8.20 to eq.8.21a.
What I would have done is sub in d[FONT="Arial Black"]l=a.d∅.[FONT="Arial Black"]a∅ and integrate ∅ between 0 and 2pi.
This would then give you...
