I am desperate with an assignment and i would be grateful if someone could answer the following question. I read about skin effect and skin depth and i found the following one. "The skin effect depends upon the nature of material used for the conductor diameter of the wire, frequency, shape of the wire. Skin depth varies as the inverse square root of the conductivity. This means that better conductors have a reduced skin depth." As i know ac frequences provokes skin depth . Higher frequecnies means smaller skin depth and high Rac Resistance and high losses . I cannot undestand why a ''good conductor'' has a reduced skin depth. I thought that good conductor means bigger skin depth, small resistance Rac and small losses.
