Answer Posted / madan
Skin effect appears in conductors carrying Alternative
currents. as its name shows, current flows through the
surface rather than through the whole cross sectional area
of the conductor. it happens because of electromagnetic
effect of AC. Due to it inductance of conductor is more at
the centre and it decreases as reaches to surface of
conductor .thats why in AC current flow on surface of
conductor.
AS we know inductance of conductor in dc is zero. so
current has no oppostion so it flow through whole
crossectionl area of conductor
