Skin effect and proximity effect formula

WebbSkin Effect: When a DC current flows through a conductor, current is uniformly distributed across the section of the conductor. On the other hand, when an AC current flows … The internal impedance per unit length of a segment of round wire is given by: . This impedance is a complex quantity corresponding to a resistance (real) in series with the reactance (imaginary) due to the wire's internal self-inductance, per unit length.
