I read in sci.electronics.design that Jim Thompson <thegreatone@xxxxxxxxxxx> wrote (in <40qn51tv3o0838tfbcs2fhi060dhht9jor@xxxxxxx>) about 'Amp output Z', on Tue, 12 Apr 2005:

Vm1/Vm2 = (Ro-jXc+Rm2)/(Ro-jXc+Rm1)*Rm1/Rm2
Since your DMM doesn't give you phase, you can't solve for Ro.

When you rationalise Rm1/(Ro+Rm1+jXc) to Rm1/sqrt{(Ro+Rm1)^2+Xc^2)} you are automatically including the effect of phase. Likewise for the similar but inverted expression containing Rm2. -- Regards, John Woodgate, OOO - Own Opinions Only.
