Different countries have diff supply voltages for household lines for power distrubution.Is one more economical/convenient for production /transmission etc than the other?(U S 110/120 volts .. U K ..220/230 volts?)How?

ok friend its a very good question. Let me tell u the answer, Its the other way arround then wht you are thinking. When u are using 220Volts distribution system you need a lower conductor size and lighter towers, that is because in 220 volts system u have lower current levels then in 110 volts.
Ok talking of tranmission and distribution losses, as a science student u know that a system of 110 volts would have higher losses then 220 volts system as higher I2R loss in 110 volts then in 220 volts.
So looks like india is on the right track.
But in underground distribution the 110 Volts sytem would have advantage over 220 volts as cable cost would be less for 110volts as it would require lower insulation.. email me if u want to know more..

I'm in a 110 volt country, but my clothes dryer is still 220 volt. Thats because the power leading up to my house is 220 and it is stepped down for internal use.
Transmission of power over long distances is more efficient (smaller wire, less line loss) at higher voltages.

Well technically (at least in the US), The power is transfered through High voltage lines, a transformer steps it down, when it comes into your house, it comes in at 220 volts. Your breaker panel is were it is seperated to 110, or 220 volts. Other countries also have different cycles in the ac wave length. We use 60 cycles per second, Europe I belive uses 50 cycles per second. That might have something to do with different transmission voltages.

Advantages of using 110/120 volts against 220/230 volts are: it is less harmful to humans,especially human life is not at risk; secondly there is no risk of insulation failure.
Disadvantages: Diameter of the conductor increases and hence cost will be more,and the weight of the conductor also will be more.

110 supplies, having lower voltage, require more current to do the same work as a 220 supply. Therefore they require larger gauge wire for the same application. More copper = more money. On the other side, lower voltage = less danger. That's about it.

An electrician friend put it this way, regarding touching a live wire, learned the hard way:
440 VAC kicks you away.
110 VAC definitely gives you a buzz, but probably won't kill you.
220 VAC makes you stick...roasting like a weenie.
The higher the voltage, the more efficient the transmission as well as requiring a smaller (lighter, cheaper) conductor.

Apart from the distribution, the 110V is less dangerous than 220V when we accidently touch the terminal.
So, it is a trade-off of using 110V with more heavier wire for a comparatively safe voltage.

The electrical losses are smaller for higher voltages but it is more dangerously.The utilized power it is:U*I and the losses are:R*Ipower2.Increasing U,for the same power utilized,I decrease and the losses,much more,also.The voltage increase it is efficiently up to 500,000V,when another losses stop this.

im not sure. i think it requires less current.
