Why the total reactance becomes more capacitive?

Hi Pierre,

The total reactance before you shrank the wire diameter was balanced
at zero (presuming a resonant structure). After the wire diameter was
made smaller, for the same length, the inductance was lowered. Less
inductance to balance the existing capacitance leaves an excess
capacitance you observe. Of course, by making the wire thinner also
changes capacitance, the change in inductance moved further.
