Answer / sudipto jena

Hello friendz, this is sudipto,from rourkela
skin effect is the tendency of AC current that it is
distributed in such a way that the current density is largest
at surface of the conductor and decreases towards core.
Now u can answer ,why conductors comes in strands in stead of
single wire.

Answer / dorji

If i answer to no.1
Conductors comes in strands coz, larger cross section of conductors can be used & on other hand if we happen to use single wire then, as said above the density of current will be high at the surface(skin effect), it means it uses only outer part of the conductor and no full utilization of conductor.

if there is nutral in phase why we use earthing wire and grounding? even at fault condition the fault current flows to neutral (it is a lower path)
