Well, it does vary a bit from place to place, but the general answer is that these are 2 and 4 times household voltage ot 110. For engineering reasons, it's easiest to transform voltage in steps of two (the same transformer can then be used for both two and three phase loading). The higher the voltage is, the more efficient it is to conduct over long distances. However, higher voltages are also more dangerous, so a trade-off is made. Typically, power to your neighborhood is 440, to your house is 220. That's used directly for major appliances, but stepped further to 110 for most outlets. 110 was simply choses as the lowest (safest) voltage to route things around the house efficiently using reasonably sized wires. The Europeans disagree and use 220 or something for everything. 220 is considered scary stuff by most Americans.

a relentless contemporary means supply is rather an consumer-friendly means supply with a contemporary limiter. that's used for contraptions that would grab too lots contemporary in case you merely positioned a voltage in. In training you have got severe voltage and what the means supply will surely do is variety the voltage to get to the contemporary which you positioned. For an appropriate means suply the voltage will attitude infinity as you improve the resistance of the burden. For a actual PSU whilst it gets to its maximum voltage then contemporary will drop.

It isn't.
Single phase global voltages are typically in the 100-240Vac range With most voltages grouping around either 120V or 240V depending on where you live.
Europe for example is gravitating toward standardized 230Vac.
In the US and Canada the standard is 120V. Specified minimum is around 108Vac with typical voltages at peak use during the day or 108V to 120Vac.
3phase power will yield 120V, 208, 240, 347, 415, 460, and 600 depending on the configuration.

well ur assumption or what can i say that ur theory is wrong that voltages are distributed an multiples of eleven.......we have to decide a particular value at distribution level which in india is 220v 1-ph for residential users & its 400v 3-ph for industrial users .............so its not necessary that voltage supplied is in multiple of 11

it would be tens, but there is a loss during transmission and conversion, so they keep increasing it to compensate, As the use goes up and capacity doesn't, it will increase. with most AC equipment low voltage is worse than high, so they just keep going higher.10% higher is acceptable. !0% low is bad.

Perhaps because in India power generation is at 11 KVA.

Great question! I am curious myself, but I don't know the answer. Being too lazy to do the research myself :) I starred your question, and will be reading the answers you get. If you don't get a legitimate answer, let me know and we can research it. Good luck!

ItS NOT REALLY......only that we only like to use that kind of voltage.......you can create your own volt at home if you like....
