Not all frequencies are created equal. Should I create a device and want it to resonate at a low frequency I must use a large capacitance which must be charged and discharged. If it resonates at a high frequency, I must expend energy to switch and low values for RC time constant timing bleeds energy due the need to use low resistance. The low C component also makes the device more unstable since small changes in capacitance will throw it out of resonance. If my device dictates its own resonant frequency then I must invest time trying to learn to build adjustable frequency circuits which will invariably require changing capacitors or resistances to address component specific variance that changes over frequency.
Let's call this the frequency conundrum. Is there a frequency or range of frequencies which because of natural laws consume less power and require less capacitance for commonly encountered inductance? Assuming that the natural laws of the Universe aren't entirely linear this is the frequency I'd like to target. By standardizing my devices on an efficient frequency I can design circuits that are naturally more efficient.
