Doesnt resistance mean same as impedance??

     "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

The resistance is related to a DC circuit.  The impedance is related to an AC circuit.When we talk about impedance we should consider capacitive and inductive elements in the circuit.  Measuring the impedance of a speaker driver will show a difference between the DC value of the voice coil and measurements taken at different frequencies showing the behaviour of the inductive part of the coil in action and the capacitive part of the whole. The DC measurement is taken when, for exemple the speaker driver's cone doesn't move (static) while the AC measurement of impedance is taken with a sweep of frequencies (10 Hz to 10k Hz).  A 8 ohms impedance woofer may have 6,5 ohms of DC resistance. I hope it helps to clarify the difference.

     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).
