Hi,
There is an equation relating R(AC) to R(DC) for a coil of multiple layers.
This is on page 18 of AN-53 as follows

“m” is said to be the layer number, but surely the resistance is more in the middle layers, and less at the outer layers, and the equation doesn’t account for this?
Also, it says “h” is the layer thickness. Does that mean the diameter of the wire?
