Answer / kareesh

rms value= formfactor*averagevalue
form factor =1.1
so volatages are always multiples of 1.1

Answer / satyavir

Because we have allready asume that voltage drop in line
will be 10%.so after losses in voltage we can get at the
source point in the series of 100v,200v,400v.so we use
110v,220v,440v,voltage series.
