Default Distributed capacitance effects Q?

Just out of interest, if you increased the inductance to 10.9uH by
increasing the number of turns, what effect would it have on the Q?
Ian.


Ian, that depends on the type of coil.

A very simple view (eg if a toroidal core was used) would be that it would
take a (10.9/10)^0.5 increase in turns (4.4%), inductive reactance would
increase by 9% and R would increase by 4.4%, Q would increase by 4.4%.

I don't really understand the relevance of the questions.
