Hi Dave,

No, it's not the same top to base. This distribution of current can (for
a lack of terms at this moment) congregate in an area (or disperse in an
area) as compared to other parts of the winding. The frequency of the
coil is part of that situation. Current nodes do occur, and thus voltage
nodes. Paul's done some great work to explain this better than I can.
One of things that occur is a difference of inductance at Fres as
compared to a semitrical distribution of current where we can easily
measure Ldc. But at Fres, the inductance has changed a bit due to the RF
situation. Javatc shows this as Les.

If your further interested in this subject, I recommend visiting Pauls site:

Take care,
Bart

Nicholson made some fundamental mistakes with his analysis, there is no Fres
or Fes
these are entirely mythical.

Inductance only occurs in regions of voltage. So for example if we have
conditions where a half wave exists. we have two regions of inductance where
the LC response is dictated by each region.

We have pointed this out years ago and they paid no attention. ( foolish
arrogance)
