% Find enhanced AC wire resistance due to skin effect
Used to find eddy current losses. In the limit of long skin depth,
reduces to DC resistance. In the limit of short skin depth, reduces to
resistance of a thin layer on the outside of the wire.
Type ACResistance for a demo
--------------------------------------------------------------------------
Form:
ACResistance; % demo
R = ACResistance( f, d, rho )
--------------------------------------------------------------------------
------
Inputs
------
f (1,:) Frequency (Hz)
d (1,1) Wire diameter (m, default AWG 10)
rho (1,1) Resistivity (ohm*m, default Copper at 20 C)
-------
Outputs
-------
R (1,:) Resistance per unit length (ohm/m)
rhoEff (1,:) Effective volume-averaged resistivity (ohm*m)
