what is the physical phenomenon because of which skin
effect occurs ??
Answer Posted / arindam paul
skin effect occurs due to nonuniform flux linkage in the
conductor portion. thus inductance of conductor portion is
not uniform i.e. at the conductor surface inductance is low
and at centre of the conductor is maxm. so current density
at centre is minimum and at surface it is maximum. Due to
increment of frequency this effect is more pronounced.
For dc current there are no skin effect.
