Here is my question to the list.  Does standard electrodynamics theory
identify these three different resonances for any given LC
combination?  Also, have these three types of resonances been fully
investigated and their functions identified?

Dave:

	Need some more detail.  Describe the test setup and the observations which go with these resonances.  A circuit comprised of a oil with pure inductance (no distributed capacitance) and a capacitor will exhibit highest (infinite if there is no loss) impedance if the two are connected in parallel and the impedance is measured across the combination.  If the two are connected in series the terminal impedance will be zero at resonance.  A series circuit consisting of an inductor with some parallel capacitance in series with a capacitor will show an input impedance which peaks at one frequency and is zero at another.  Were you inductively coupling to the coils; that can lead to somewhat different results?  What were your measurement techniques?
