Matt,
When an inductor is placed in series with an AC source it causes
resistance governed by this equation. R = 2 * Pi * f * L
So for a transformer that uses about 1kw you would need 14.4 ohms with a 120
volt wall socket, so the inductance should be about 0.0382 H, so on a 12 in
cylinder with a 6 inch diameter you would need about 780 turns with air as the
core. I don't know how to figure out the internal resistance of the
transformer.
Somebody correct me if I am wrong. Like everybody wouldn't if I was. :)
