"Q" [Figure Of Merit most of the time] can either be applied to the VD formula as Skin Effect Ratio / Calc, or used in conjunction with Reactances [Xl &/or Xc] to determine an Impedance.

It's in one of my EE books some place [Linked Image]

"K" is typically for "Constant", as indicated by Doc, and is Conductor dependent.

Are you planning to calc a Voltage Drop using the "Complete AC" method - which applies the Power Factor, Total Conductor Impedance [Resistance and Reactance(s)], Conductor Type [Skin Effect] and Magnetic / Non-Magnetic raceway?
