Hello,
From Wikipedia:
"For wound components such as inductors and transformers, there is additionally the important parasitic effect of capacitance that exists between the individual turns of the windings. This winding parasitic capacitance will cause the inductor to act as a resonant circuit at some frequency, at which point (and all frequencies above) the component is useless as an inductor."
My question is, why would it say that "and all frequencies above" as I thought that the point of resonance is a specific frequency where inductive and capacitive reactance cancel each other out, and above or below that, you would still get the reactance effects (if so desired)?
