Similar to Eq. (6.1) we have for periodically oscillating electric voltages
and loads and the relation
[6.1, 6.12]
Here
are the Laplace transforms of the charge (Q(t)) and voltage (U(t)) at the
capacitor, and is a complex frequency with
[6.12]. The frequency dependent complex capacitance
defined by Eq. (6.3)
