Just keeping it real
Everybody going on about 110/220 V please get with the program. It's been 120/240 V nominal at the entry into the house in the USA for simply ages. It's actually only spec'ed +-5%, so anything in the range 114-126 V is in spec for the supply. Equipment must be capable of working without appreciable handicap anywhere from 110-130 V. Most computers and TVs are perfectly happy working with 90 V or less, up to at least 130 and very often over 240 without any circuit switching.
I am informed that the UK is 230 V, so the ratio is not "over 2.0"; not even exactly 2.0, but rather less than 2.0.
I have a very strong memory of reading that the nominal voltage in the US used to be 110/220, but that was at least 50 years ago. I cannot now locate any trace of information on the web to that effect.
