Check the back; if the power supply has a switch that lets you select the voltage the PC can be used either in the US or Europe. If it DOESN'T have the switch, read the manufacturers literature to see what's required. you may need to replace the power supply, depending on what you have.
yes
as far as i know yes
if u had the right power addapter
You can use the actual Wii in the US, but you can't use any games that are bought in the US with it, as it is classed as a different "region."
How dumb do u sound?!? Of course u can
No
Yes, a digital camera bought in the US would work in the UK or any other country for that matter. You would have to buy an adapter to plug into the wall when you use your battery charger (if you use rechargable batteries) because the electrical voltage or frequency or whatever is not quite the same as ours in the US.
No, different voltages, we have 230v supply, US 120v. There would be a big bang and lots of smoke, I did it at work once!
no because UK runs on a diffrent voltage system
It will work if you can get a UK power adaptor for it, and if you have a NTSC compatible TV, but you will only will be able to play games from the US, not ones from the UK.
It will work in the UK just get a US to UK travel pin adapter to so it plugs into the UK mains.
Yes an Iphone if bought in hong kong worked in the uk. because it only depend to the user if he/she knows on how to used it...
