TEXT 824 -2976 Left 0 ;skin/proximity effect\nTo understand, first realize that a conductance \nis just a voltage controlled current source.\nThis voltage controlled current source senses the \nvoltage drop across it and calculates the allowed \ncurrent using the Laplace option.\n \nRdc is the dc resistance of the wire.\nFskin is the frequency where the skin\neffect has in increased the resistance\nby a factor of 1.19
