What do we do when we are finished with the draft and ready to publish?

Does anyone know why my LaTEX stuff is changing sizes throughout my article? An Ideal Transformer Example

(John Hawkins) As I understand it, the text is made full size (larger) if there is ever a function call, i.e. something starting with a backslash, excluding some things like greek letters. I have just put "\ " (the function call for a space) at the beginning of an equation and had it work. If you don't want to change anything about your equation but just want it displayed full size, type "\,\!" (small forward space and small backward space) somewhere in your equation.
Thanks John!

If anyone wants to write the derivation of Ampere's Law you can put it on my (Wesley Brown) Ampere's Law page and be a co-author.

What is the input impedance of an idea transformer with two secondaries, one with N2 turns and one with N₃ turns, each with a different load resistor on attached.
How do the mutual impedances relate to the turns ratios?
Develop a circuit model for a non-ideal transformer with multiple secondaries.

Describe the coupling factor, k, used in Spice simulators and other circuit simulators. Relate it to the leakage, magnetizing, and mutual inductances.
Derive the $Y/\Delta$ transformations.
Explore the voltage regulation $(V_{full~load}-V_{no~load}) \over {V_{full~load}}x100\%$ as a function of the power factor angle on the load of a transformer. (You will note some surprising results in some cases.)
Describe the open circuit and short circuit test as applied to transformers.
Calculate and compare how much power can be delivered with three phase circuits as compared to a single phase circuits. Assume that the same amount of copper wire is available for both systems.

These articles are not ready for reading and error checking. They are listed so people will not simultaneously write about similar topics.

These articles have been reviewed and submitted.
