The most basic reason to use 220 instead of 11o is that for a given load Watts= Volts x Amperes Double the volts and you will halve the amperes. The rating of wire is the amount of amperes it can safely carry. Less amperes means you can use a smaller wire size. This will save money on the initial installation.

∙ 10y ago110 v intead of 220 v is a choice made by governments for their own reasons. 110 v tends to be inherently safer but requires more current to carry an equal power, so more copper is required in the thicker wires used in houses. The USA uses 120 v.
In Europe 220 v or higher is used, which economises on copper wire but it requires more stringent regulations for wiring and equipment to protect the users from the higher voltage.

How is 220v water heater rewired to 110v?
Use a transformer to lower from 220 to 110V.
Can you use the 220v 50hz appliances in 110v 60hz?
Depends. Some smaller stuff can usually run on both, in which case it will be printed on them. If it isn't, you can't run a 220v item on 110v.
Plug a 110v hair straightener into a 220v outlet?
Do not do this.
Can you use a 220v outlet to plug a 110v electronic device into?
You cannot directly plug a 110v device into a 220v outlet. This can cause damage to the device or even create a safety hazard. You would need a voltage converter or transformer to safely convert the 220v outlet to the appropriate voltage for the 110v device.
What causes a 220v wire to pull only 110v?
The fact that it's supposed to. Voltage is stated as the difference between the two wires carrying electricity to the load. When they bring power to the house from the utility, you get two wires carrying 110v but they're 180 degrees out of phase. Imagine one carries positive 110v and the other carries negative 110v. If you hook one of these wires plus a neutral (zero volts) to the load, you get 110v--110v over 0v. If you hook both of them to the load, you get positive 110v over negative 110v, or 220v. So...red to white is 110v, black to white is 110v, red to black is 220v.

Can you use your canon mx340 printer with 220v and 110v?
Yes, it will work on either voltage.
How do you convert agenerator of 80kva with an output of110 v to 220v?
Best way is to use a step up transformer to step up the voltage from 110V to 220V
Can you attach an iron machine of 220v in a 110v socket?
No
Plug a 110v hair straightener into a 220v outlet?
Do not do this.
Can you plug your 220V electric piano into a 110V socket?
No.
You bought some electronics in China which requires 220v In that case can you use these devices in Canada which uses 110v without getting a voltage converter to convert from 220v to 110v.?
No.. you can't... You will actually be damaging your instrument.. It is highly recommended that you use voltage converter... I think it is not too costly
Why are you applying 110V instead of 220V while finding Rth in thevenin's theroem?
by applying 110v at the output terminals by closing switch s2 to 'dd' .read the voltmeter(v) and ammeter(I) and get Rth=V/I.
Why 220v and 110v was chosen as standard voltage in Brazil and not some other voltage?
220v and 110v are almost the only voltages used around the world because they are the most efficient.
