I guess I used that word because I maybe misunderstood diagrams like the one on this page. I'm not so sure about "dynamic" or "small signal" resistance though for this particular case. What if I replaced "impedance" in my answer with "effective series resistance?" | |
| Oct 13, 2021 at 1:09 | comment | added | Alfred Centauri | Hi Solomon, is it the case that impedance is defined as $Z=\Delta V / \Delta I$? In my recollection, as an EE old timer, the quantity on the right hand side is an approximation of the so-called dynamic resistance or small-signal resistance. Impedance, on the other hand, is a complex quantity defined as the ratio of the voltage and current phasors associated with a circuit element in AC steady state. | |
