Here is a odd one. Can anyone know a way to calculate the resitance or impedence (for the politically correct) of an AC circuit that that is unbalanced which will result in resistinace due to CEMF? Thanx

CEMF in a ordinary stationary piece of wire is simple straight-line inductance. NEC has tables in the back for most cables already. It gets more complex if you're talking about motors and other moving magnetic fields.

And yeah, this is certainly the right time to call it "impedance!"
