Some countries (Europe, Japan) use 120 volt systems. Australia uses 240 volt. One way of find out what voltage is used is to have a look at the pins on the appliances in the same area. 120 volt has round pins on the plug socket. 240 volt systems have 3 flat blades with rounded ends set at 30 degrees to each other around the centre of the socket
If you are in the US and have a residential 120/240 volt system and want to know if you should use 120 to ground or 240 volts phase to phase. You should check the voltage rating of the equipment you are wanting to use. Never exceed the voltage rating.
No, it is not possible to use 240 volts with a 120 volt supply directly. You would need a transformer to step up the voltage from 120 volts to 240 volts. Attempting to use 240 volts with a 120 volt supply without a transformer can damage equipment and pose a safety hazard.
Try at a electrical wholesale outlet. Don't know why you would want a auto transformer. A standard 240 to 120 transformer usually does the job and it can be run backwards or forwards. 240 primary 120 output on secondary or 120 primary 240 output on secondary. Either way you will have to know the amperage of the load to get the correct size of transformer.
The household supply in the UK is 240 V and is AC (alternate current).
On a 120 v supply it takes half an amp, because 120 x ½ is 60. On a 240 v supply it would be a different bulb, designed to work on 240 v, and it would take ¼ amp.
On a 120 v supply 320 watts is 320/120 amps, or 2.667 amps. On a 240 v supply the current is 320/240 amps, or 1.333 amps.
No, but check the specification on the power bar to see what its maximum voltage rating is. There will be a bit of cord end cutting to get the right configuration for 240 volt equipment.
To convert a 240 volt power source to a 120 volt power source using a 240 volt to 120 volt adapter, simply plug the adapter into the 240 volt outlet and then plug your 120 volt device into the adapter. The adapter will step down the voltage from 240 volts to 120 volts, allowing you to safely power your device. Make sure the adapter is rated for the appropriate wattage to avoid damaging your device.
A machine that operates on 120/240v 3 phase power requires a power source that can provide both 120 volts and 240 volts of electricity in a three-phase configuration. This means the machine needs a power supply that can deliver three separate electrical currents, each at 120 volts and 240 volts, to operate effectively.

European lamps work on 230 v (240 v in the UK). In the USA the supply is 120/240 v with low-power appliances like lights running on 120 v. But 240 v is usually available in a US house so see an electrician.
On a 120 v supply 320 watts is 320/120 amps, or 2.667 amps. On a 240 v supply the current is 320/240 amps, or 1.333 amps.
There are 240/2 = 120 of them
If "100 to 240 V" is stated on the rating plate of a small electrical appliance, such as an electric razor or a plug-in power supply for something else, that means it is designed to operate on any voltage between 100 Volts and 240 volts. * So the appliance will work if it is plugged into a 120 Volt household AC power supply in the US, Canada or elsewhere in the world which uses a similar supply and * it will also work on a 230 Volt household AC power supply in the UK or any other country in Europe or elsewhere in the world which uses a similar supply.
Its all in the power supply. If there is a switch that lets you change the input voltage from 240 to 120 then you are fine. Most computers have this switch on the power supply, its located on the back of the computer up by the top. All you will have to do is change the plug on the cord to fit that country's 120 volt receptacle.
