Yes, as the voltage goes higher the amperage goes lower. With a lower current the wire size can be smaller and in the case of a motor the equipment to start and stop the motor can be of a smaller size. This equates to a savings in the installation costs.

The standard European residential nominal ('named') voltage is 230 V. Although this means that, for a given load, the current is lower (about half) than it would be for a North American 120 V supply, in practise European residential conductor sizes are not much different from those in North America. For example, a North American receptacle or socket outlet is rated at 120 V/15 A, a British socket outlet is rated at 240 V/13 A, which means that whereas a North American receptacle can only supply loads up to about 1800 W, a UK socket outlet can supply loads up to about 3000 W. As a result, a British kettle, for example, is typically rated at 3 kW -enabling it to boil very much faster.
No, the Norelco 905RX is designed for 110-120 volt outlets and should not be plugged into a 220 volt outlet as it may damage the device. It's recommended to use a voltage converter or transformer that is suitable for your particular device in order to safely use it with a 220 volt outlet.
Answer for USA, Canada and countries running a 60 Hz supply service.Breakers are rated in amperage and by the amount of poles that they have. Your classification of a 220 breaker is described in electrical terminology as a two pole breaker.Choosing the amperage of the two pole breaker depends upon the 220 volt load that it feeds.Two pole breakers for 220 volt loads.Single pole breakers for 120 volt loads.If the service is only 120 volt then every other bus bar in the panel will be energized. If the panel is a 120/240, then every bus bar in the panel will be energized.This is how and why a 240 volt load requires a two pole breaker.To the answer, yes you an use a two pole breaker in a 120 volt service but only one side of the breaker will have voltage on it depending on where it is situated in the panel board.
No, it is not safe to plug a 220 volt heat pad bought in China into a US 120 volt outlet. The voltage difference can damage the heat pad and pose a safety risk. You would need a transformer or voltage converter to safely use the heat pad in the US.
No, you cannot directly get 220 volts from a 120-volt outlet. You would need a transformer or voltage converter to step up the voltage. Make sure to use the appropriate equipment to avoid damaging your devices or creating a safety hazard.
To change a wire from 220-240 volts to 110-120 volts, you will need to reconfigure the wiring by connecting it to a transformer that steps down the voltage. This transformer will reduce the voltage from the higher range to the desired lower range, allowing you to safely use it with 110-120 volt systems. It's important to ensure the transformer is compatible with the current and wattage requirements of your device or equipment.
no , it will burn out
Yes a 220 volt light bulb will run on a 120 volt circuit but at 1/4 of the wattage that the light bulb is rated at. A 100 watt light bulb on 220 would would be equal to a 25 watt light bult on 120 volt system.
you don't. you just take and use 120 volts from the 220. At least that's what I'd do.
Yes, this can be done. The adapter will handle at 120 volts x 15 amps = 1800 watts. The adapter is just a step up transformer. The maximum 220 volt device that can be connected can only have an amperage rating of 8 amps at 220 volts.

If a motor is designed to run on different voltages there will be a wiring diagram on motor plate for 120 volt wiring. If not you will have to use a step up transformer to convert 120 V to the higher voltage.

The voltage cannot just be increased in a circuit because there is a risk of damage, blown circuit breakers and/or fire. However an appliance desgined to run on 220 v will use 6/11ths of the current used by an identical appliance designed for 120 v.
Yes, in fact that is what a rough service bulb is rated at. The bulb used on a 120 volt system will have a reduced wattage output as to what it would be on 130 volts.
