in 110v we require more transformers each supplying smaller localities. during power failures less houses are affected.
in 220v fewer but huge and efficient transformer are required each suppling a larger locality. Transmission losses are 4times less than at 110v.
so PERHAPS it is due to india's huge population and demand; and considering the cost of setting up more transformers and the efficiency factor

Most countries in the world operate at 110 - 127 Volts, there are pros and cons to each system, operating at 220 V means you will use half the current needed to operate an electrical device, however electric shocks are much serious than those at 110.
You can always use a transformer to increase / decrease voltage to suit your needs.

Where is here? 220 is better for operatin high amperage appliances because you get charged for the "high leg" and 220v draws equally from both legs of the box. if you ran everything 110v you would end up paying more for you electricity.

not 110.
Japan is 100V.
Think about. What volts does your digital camera need at the end of the limb?
6V ? 8V?
How about TV? A/C? etc?
Today most electronics can work efficiently with100-120V, which US, Japan. Taiwan..etc. take.
But it is almost impossible to change the voltage through the nation today.
