Doesnt resistance mean same as impedance??

     Correction:  Not my, "initial post", but: the two I made 01-08.

     However (beyond that simple wire): as the reference materials in my second post on 01-08 and my last post mention*: resistor values also fluctuate, with changes in voltage, which will include any sinusoidal waveform (ie: AC).

                                      *Voltage Dependence

                           Argue with the science, all you want.

     "There is NO frequency with DC, which is WHY, "resistance is constant".

     "The above is NOT true. You can still apply AC to simple resistance and its resistance will still NOT change,..."

                         I CLEARLY said, "frequency", NOT, "AC".

     Note figure 2, here:

      Then there's:

     Aside from that: I was addressing why the terms differ, not specific components*, in my initial post.

                  *Outside of the simple wire and AC, that I mentioned

     As noromance put it:

     Resistance = DC

     Impedance = AC

     SIMPLY: the semantics applied by the scientific community to measuring electrical flow, as concerns those two types of current and their performance through conductors.

                         btw: DC = no waveform, while AC= sinusoidal

      Perhaps some fail to understand that, in any sinusoidal waveform, VOLTAGE rises and falls, changing the math completely.

             ie: https://www.electronics-tutorials.ws/accircuits/ac-resistance.html

     "Impedance is resistance which changes with frequency whereas simple resistance is constant with frequency."

     There is NO frequency with DC, which is WHY, "resistance is constant".

     With ONLY a single strand of solid wire: passing an AC current (ie: with a frequency) through, will cause that wire’s effective cross-sectional area to be reduced, via skin effect*, thus: an increase in measured Ohms (knowledge regarding electricity that has been around since the late 1800s).

                    * https://en.wikipedia.org/wiki/Skin_effect

      Even you wiki-scientists should be aware of such a basic electrical measurement!

                                      As mentioned, perhaps: easier to digest?
