Wire diameter vs Impedance

wrote: 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. 73's Richard Clark, KB7QHC |
