I think Don is right: the resistive load measurement is not useful; yo need
to measure the e.m.f. and to perform two reactive load measurements in
order to solve the equations.

Does anyone know of a source of test equipment, purchase or rental, or a

I did that once. I had been measuring resistance and then needed to measure
ac outlet potential, but forgot to change the meter knob position. Now I
have a new meter.

'Measuring AC Line
Hi Dave:
I had the same question some time back, and came up with the following process.
1) For the resistive component, I applied a resistive load to the AC line, and
calculated R = dV/dI
2) For the inductive component, I measured the transient current through an 'X'
capacitor at the moment
In a message dated 9/19/2002, you write:
So far, I've taken a large resistive load and measured the voltage drop on
the AC line. From that I calculated the total impedance of the AC line.
However, as you may suspect, with a resistive load, the power factor is
1.0.
So I can't vectorly,
