Many sources I've read state that reactive power is important because it helps maintain voltage and magnetic fields in inductors, but in a circuit at its resonance frequency, the inductive and capacitive reactances should cancel so there would be no reactive power. What happens in ...
The larger an inductor’s inductance, the greater the capacity to store electrical energy in the form of the magnetic field. How Do Inductors Work? The inductor in a circuit opposes changes in current flow through it by inducing a voltage across it which is proportional to the rate of ...

, maintaining the needed boundary conditions on the walls of the cavity. Due to these boundary conditions that must be met at resonance (tangential electric fields must be zero at cavity walls), as it follows that cavity length, it must be an integer multiple of half-wavele...
While a real-world capacitor has an equivalent series inductance (ESL) due to the leads and package. As the frequency increases, the ESL also increases, whereas the impedance of the capacitive element decreases with increasing frequency. At a certain frequency (the self-resonance frequency) the ...
