Once upon a midnight dreary, Philip.Belben(a)pgen.com had spoken clearly:
This means, among other things, that (for sinusoidal
ac) the flux is zero
when the voltage is at its peak and vice versa.
Which, in short, is why a transformer doesn't work with DC.
[Editor's Note: No, this little blurb is just to show I know a little about
these things (now) -- when I was young (10-11) I designed my first xformer
- right number of turns to it and everything! I hooked it to a 6V lantern
battery - and couldn't figure out why there was no voltage coming from the
secondary coils. 'Course, the Internet was unheard of by normal folk, and
we hadn't a lot of money so I had no books, save a "How it Works"
encyclopedia set that I had, that showed a beautiful breakdown of a xformer
(which I modeled mine from) - but failed to mention it needed AC to
actually work!]
Thank you for an excellent description (or should I say dissertation?? ;-)
on the whys & workings of transformers!
Happy Holidaze, and have a good niner-niner,
