in rich contry having not any problem of mony.

mostly uses 110 volts of supply.

bcose in 110 volts supply power loss is grater as compare
to 220v supply(india)
p= V Square/R

power is inversly propotional to resistance if we consider
voltage.



If human safety has to be consider than definately 110
voltage system is more safer than that of 220 volts.


if energy saving is considered then 220volts is batter then
110 volts(u.s.a)
