Why do we have 110V, 230V, 415V etc. in electrical
transmissions? Why not 100V, 200V,400V?

Answer Posted / 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.
