"Ed what you are talking about is dialectric heating and it has
nothing to do with resistance (D.C. resistance) if you were to put an
oh meter across that capacitor it would probably read in excess of
100 meg ohms! The dialectric losses or power factor losses as they
are sometimes called are due to the dialectric absorbing the R.F."
        Correct.  Never said it was SERIES ohmic resistance.  Point
is that ferroelectric ceramics such as the titanates used in the
capacitors do have appreciable hysteresis in their electrification,
producing an effect analogous to hysteresis loss in magnetic
