8.16 H.F. Resistance
All these causes of loss in high-frequency circuits come within the
general definition of resistance (Sec. 2.18) as (electrical power
dissipated)
-r-
(current squared). In circuit diagrams and calculations
it is convenient to bring it all together in a single symbol such as r in
Fig. 8.9α in conjunction with a perfectly pure inductance and
capacitance, L and C. But we have seen that at resonance the whole
tuned circuit can also be represented as a resistance R = L/Cr (Fig.
8.96). We also know that a perfect L and C at resonance have an
infinite impedance, so could be shown connected in parallel with R
as in Fig.
