WhatsAppWhy do larger capacitors (more capacitance, same package) have a more gradual shift from decreasing to increasing impedance while smaller caps have a sharper change? The sharpness is the Q of the resonance. (sharper = more Q) L is a function of the size, so L is roughly constant for a given capacitor body/lead size.
WhatsAppOnce things have settled out, there is no more change, and they have no further effect. So in the long-term, steady-state, capacitors and inductors look like what they are; they act like you''d expect them to act if you knew how they were constructed, but didn''t know capacitance or inductance even existed. An inductor is a wire.
