Abstract :
A new exact integral equation pertinent to the calculation of the skin effect induced internal impedance of a straight conductor, based on the correct boundary assumptions, is derived. Applied to a circular wire, it is shown that the exact internal impedance is persistently underestimated when employing classical techniques such as quasi-static approximation.
