In my calculations I was assuming no losses, too, so it doesn't
work, in
any case.

Daniel

The diagram I drew at http://petersphotos.com/temp/transformer.jpg makes
perfect sense to me.

If you create a secondary coil in the lower half and seperate the two
circuits, it's just like a normal transformer.

If.....If.....If

What you drew *Will not* work! No if's, no but's, no maybe's!!

Ok, please redraw my diagram showing me where you think the currents
travel.

Scott, I don't have great graphics skills, but:-

If you joined the primary and secondary 0V wires, you are left with a
three contact transformer!!
In your diagram the current for the load should go the other way.

Yeap, so it should!! My mistake!!

I still don't know what you're saying is wrong with my diagram http://petersphotos.com/temp/transformer.jpg

The tired doctor was awakened by a phone call in the middle of the night. "Please, you have to come right over," pleaded the distraught young mother. "My child has swallowed a contraceptive."
The physician dressed quickly, but before he could get out the door, the phone rang again.
"You don't have to come over after all," the woman said with a sigh of relief. "My husband just found another one."

What!! Apart from me saying *it will not work!!*

In my diagram, the 1.5A primary current flows &only* in the primary
winding of the transformer and the 3.0A secondary current flows *only*
in the secondary.

Whereas in your diagram, *you* had both flowing in one part of *your*
coil, which would not work!!

No if's, no but's, no maybe's!!

The current flowing in my load circuit has to come from somewhere. Redraw my circuit, with the same transformer, showing where you think current flows.

Redraw my circuit, with the same transformer, showing where you think

In my diagram of a couple of days ago, I have tried to use your
transformer, with 240V applied across the primary and 120V developed
across the secondary in a manner that *DOES* work, but *you* will not
see it.

You cannot see the difference!!

Hey guys, why not check out the wiki for variacs ?
From what I see of your posts you are straying from reality!

You're not showing a Variac in your diagram. The Variac has the source voltage across the ENTIRE coil. The load is connected across HALF the coil.
