As some energy is lost due to resistance in the resonance process, the total amount of energy stored in the inductor decrements in each resonant exchange. The resonance frequency, which is the speed of energy transfer, is determined by capacitance (C) and inductance (L), as shown in Equation (15).
The inductive reactance and the capacitive reactance are summarized in Equations (12) and (13), respectively. The size of impedance in a series resonant circuit is determined as shown in Equation (14).
