In EM theory concept of skin depth is induced which is a measure of how much a EM wave can penetrate the medium, from it arises the concept of skin effect which is for EM wave but we use this to explain flow of current in conductor (most of the current flows over the skin of conductor at high frequency). But all this was derived for EM wave then why are we using it to explain flow of current,which is not em wave ???
