Q Factor

[jason]

Hello All


Say Impedance Z i = jwL + Rs
(Rs is in series and it is actually the internal series resistance,
this means inductor is an ideal one)


So if we assume this way, then does it mean jwL comes from the ideal
inductor? Not from any of the Rs at all?


If we want to find Q of the inductor
we will use Q= wL/Rs where SL(or jwL) is not involved totally in the Q

equation.


Am I right ?
Kindly enlighthen
Thank you

You do not need S or j, so the relation is Q = wL/R.
