Hello,
I have a doubt regarding dot convention in magnetically coupled circuits.
In book A, the following is stated:
But in book B, this is stated:
In book B, why the inducted voltage of the second mesh (-j w M I1) has that negative sign ? According to dot convention, it is supposed that when the current enters into the dot, a positive inducted voltage appears in the dot of the second mesh right ?
Thanks!
