You could also try this site:

Looks like it does all the standard calculations along with offset bends.

Browsing around Hyper-Physics:

"What happens to electric charge in household circuits"

"In the process, as the charge progresses through the appliance, its voltage drops from 120 volts to essentially zero volts with respect to the earth. This spent charge is then dumped to the earth through the ground wire. In the standard US receptacle, the charge at about zero volts is carried back to the electrical panel through the neutral wire and then transported to the earth by the ground wire attached to the electrical panel."

This should be corrected to indicate return to source.

You may want to go to a local bookstore and get a Pocket Ref by Thomas J. Glover

I can't begin to count the times I go to this little black book for formulas and reference tables.

We have some formulas and Calculation examples here at ECN.
Try the Technical Reference area and the Electrical Theory area.

If you have some suggestions for formulas to add, let me know.
