explain what the resonant frequency of a model non-ideal capacitor
9
+
::
10
+
it's the frequency where the reactances between the capacitor and the parasitic inductance (ESL) cancel (magnitudes same, 180 degrees out of phase)

the average power $P_{avg}$ has what relationship to voltage?
18
+
::
19
+
$$P_{avg} = \dfrac{V_{rms}^2}{R}$$
20
+
where both avg and rms are done over an interval $[t_0, t_0 + T]$
