how do skin effect is reduced when hallow cond or stranded
cond are used ?
Answer Posted / k.prakashchandra
In hollow conductor the wall (outer surface)becomes thicker
for the same sectional area ,thus offering less
resistance.In case of stranded conductor ,the strands in
alternating positions share equal currents
