There is an interesting statement in a relevant TPT article:
The Driven RLC Circuit Experiment
TPT 37, 424 (1999);
Philip Backman, Chester Murley, and P. J. Williams, Physics Department,
Acadia University, Wolfville, NS, Canada
It states, and this is *not* a word-for-word quote, my interpretation:
"If the resistance of the inductor is not negligible compared with the
reactance of the inductor at the resonance frequency then the voltage
across the inductor can not be treated as a pure reactive voltage. To
obtain the voltage due to a purely inductive reaction then you must
determine the resistive voltage across the inductor and subtract that from
the total voltage measured across the inductor. "
This article uses three equations to obtain the appropriate potential
differences from the acquired potential differences across the components.
Let me know if you need a copy.
