In the United States 240 volts is produced by two 120 volt hot wires 180 degrees out of phase. Added together the voltage difference is 240 volts. To get only 120 volts one of the hot wires needs to be replaced with a neutral wire.
That would make the voltage difference to the neutral 120 volts. (There may or may not be an existing neutral wire running to the outlet. Whether there is one depends on the purpose for which the 240 volt outlet was originally installed.)
It is often not worthwhile to change the existing 240 volt outlet - it is often best just to leave it there to power 240 volt appliances.
A licensed electrician would know how to check this for you and would advise the best action for you to take. He would use the correct size of wire to supply the current required by the 110 - 120 volt appliances you want to use and connect it to the correct sizes of circuit breakers on the main panel and also a GFCI safety device to protect users from electrocution if the room is likely to be damp or have water spray or wet floors, walls or ceiling, such as a laundry room or a kitchen. All this is necessary to comply with the latest Wiring Codes in your locality. (Town/State.)
Then you would be able to use a 110 - 120 volt appliances safely in the room in question.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

∙ 10y agouse a DC link. power electronics stuff !! so in this DC link you convert the ac 50 hz to dc than convert back this dc to 60 hz with different voltage by controlling the amplitude modulation of the inverter....got it..;)
You can now purchase a frequency converter capable of converting both the voltage from 220v(+/-10%) 50Hz to 110v 60Hz and the Hz. This unit was primarily designed for the use in American RV's sold into Europe, there is also now a 2 phase model offering 2 x 3KVA on each phase at 60Hz.

∙ 14y agoMost desktop power supplies have a little red switch on the back to switch from 120v to 220v and vice versa. For laptops, you will likely have to purchase a new power adapter.

∙ 14y agoTo convert 115 volts to 220 volts you would need a buck/boost transformer wired to boost the voltage.

What s the correct calulation for the bulb power on watts which has has a current of 0.5 and the voltage is 220v?
Power is current times voltage, so a current of 0.5 amperes and a voltage of 220v across a bulb will yield a power of 110 watts.
What should be the primisable voltage between neutral and earth in a three phase system?
It is the line to line voltage divided by 1.73. 600V / 1.73 = 347V 480V / 1.73 = 277V 380V / 1.73 = 220V 208V / 1.73 = 120V
What will happen when the shunt motor is connected across the supply line directly?
If the motor is designed for 120V or 220V whatever the case, it will function properly.If it is a 12V motor and you supply 120V it will make a mess and you will probably get hurt from flying debris!
How you convert the 220v AC to 220v DC?
You can make this conversion if a full wave bridge rectifier is used. Make sure that the diodes are rated for the voltage that is being used.
What is Indian railway transmission line voltage?
220v, 415v, 6.6 kv, 11kv,33kv,132kv,400kv
Can 120V appliance work with 220V?
120V appliance will not work on 220V. Use an instrument transformer or voltage regulator to adjust the high voltage to the desired level.
Does Brazil runs at 120v or 220v?
Brazil has a nominal voltage of 220/380V.
Can you use 220v or 120v appliances in the UK?
UK is 220v
Can you buy a 120v appliance and use it with a 220v outlet?
A high voltage will certainly damage a low voltage appliance and perhaps set fire to other things nearby.
Can you run 220V 50Hz on 120V 60Hz?
If you mean - can you run a 220v device on 120v where the 220v device needs that level of voltage to operate correctly then the answer is no. Even disregarding the frequency difference which some devices aren't affected by, the voltage difference is too great. Some devices these days, such as phone chargers, laptop power supply units etc will run happily on a voltage range from 100v up to 240v (read the label first) but they are the exception. The question is somewhat ambiguous and needs more information.
Can you use 120V lamps in Europe by just putting in a 240V bulb and a European adapter on the plug?
If all the components are rated to 220V, yes. Keep in mind that if the appliance was designed for 110V it may arc if 220 is run through it. If you don't know the device can handle 220V, don't run it at 220V. Chances are it was manufactured cleaply and cannot handle the extra voltage.
How do you get 120v from 220v socket?
You don't, at least, not legally.
What is the voltage in Slovenia?
The voltage is 220V.
If you have a computer which start with 110v so by using converter can the computer starts with 220v?
Yes. If the computer power input is only rated for 110V input, you can power it from 220V by using a voltage converter from 220V to 110V with appropriate wattage. Some computer power supplies also have a switch for setting 110V/220V in which case computer can be powered from 220V after changing the setting. Most of the portable computers/laptops have power adapters which are rated for universal voltage (e.g. my Dell laptop AC adapter is rated for 100-240V 50-60Hz).
How much voltage is used by electrical device?
minimum 230volts In formal electrical jargon, a "device" does not "use" electricity. A device is something like a switch or receptacle(outlet) that helps control or carry electricity but does not consume electricity. In the United States, voltage for home lighting and general purpose receptacles is 120v. Voltage for electrical appliances such as ranges, clothes dryers, or furnaces is 240v. Voltages such as 110v, 115v, or 125v are versions of 120v in electrical jargon and voltages such as 220v or 230v are versions of 240v.
Can you use a 120v dewalt battery charger in Europe with 220v without a voltage converter without damage to the charger or battery?
No, by doubling the input voltage to the charger which is just a transformer you will be doubling the output of the charger. Batteries like to be charged at about a volt and a half above their working voltage.
Can the 12 GB PlayStation 3 console work on either 110V or 220V?
If there is a switch on the power supply that allows you to switch between the two voltages then the answer is yes. If there is no switch then you will need to use a travel voltage adapter to convert one voltage to the other.
