Hi everyone,
I am having trouble understanding the difference between skin effect and skin depth.
I know what they are; that:
Skin effect is when there is more current flow nearer to the conductor surface as frequency increases, rather than utilizing the whole cross sectional conductor area.
Skin depth is 1/e or 37% of the outer surface current density value (the maximum current boundary at the perimeter of a wire).
I know that skin depth is different for every conductor,
However I can't understand how skin depth is different for different frequencies.
If the skin depth is 1/e or 37% of the outer surface current density value, and
this outer surface current density value is the same/constant for all frequencies,
hence 37% of this value will be the same too for all frequencies??
Or is there a problem with my reasoning?
