The majority of countries in the world run the residential AC mains in the vicinity
of 220, 230, or 240 volts.
The highest nominal supply is 240 volts AC, in all of the following countries:
Brunei
Cook Islands
Cyprus
Fiji
Gibraltar
Guyana
Isle of Man
Kenya
Kiribati
Kuwait
Liberia
Malaysia
Nauru
Nigeria
Oman
Qatar
St. Lucia
Seychelles
Tonga
Uganda
The UK
400KV
A: NO the power output will be higher. Bridge rectifiers do not provide more voltage output it just add more power by rectifying both positive and negative voltage of the AC input
The laptop has a power supply that connects between the laptop and the wall outlet. Looking at the power supply, the input voltage will show a working voltage from 100 to 240 volts. You may need a pin changing adapter because the pin configuration is different between 110 outlets and 220 volt outlets. Get past the pin configuration difference the computer will operate on both voltages through the power supply as long it is in the voltage range stated above.
the government is the highest form of power in the land.
Voltage drop depends on the size & length of the wire and the wattage of the bulbs. If they make an LED replacement bulb , you would hardly notice the voltage drop.
Desktop computers all come with a power supply that changes the mains voltage in your country's electricity supply to that needed inside the PC. Thus the Voltage used by your PC is the mains voltage in the country where the PC was sold.
Normal voltage for 120volt outlets is 110v to 130v. It would vary depending on the length and size of the wire to the nearest power company transformer, and the different voltage terminals on the transformer that the power company connects.
Check the fuse
Every country has a different voltage of power source. It's better to use always an adapter if you don't know the voltage of power source of such country to avoid frying your devices.
The express type buses do have 110 outlets.
the work is done in the power supply box (the metal box part in the computer, the one you plug the power cord into). It converts AC to DC via transformers, rectifiers, and voltage regulators and has extra circuitry in there to make sure that the voltage doesn't ripple (with the changes in the AC voltage) or spike (e.g., when you first turn it on)
