Why has Europe a Different current to the Americans? 230V - 110V?

Question

would like to know how many amps the Europians use and how much do we use? and does any one know the Why is it Diffenent answer. and do you know any good books on the subject.

Answer 1

ok, listen, the higher the voltage the lower the amperage, always
60w bulb@120v = 1/2 amp consumption
60w bulb @ 220 = 1/4 amp consumption
amperage is what you pay for
if the cost is doudle in the uk than u.s. then you pay the same
in canada houses are fed 2 lines of 110 and do use 220 appliances
as for how much the countrys consume, well idont know..
and why its different, i dont know either

Answer 2

Not only dose it not make sense, it’s costly. Example, ppl moving from England to the U.S. and bringing electrical items, will have to buy an adapter for the plug and a transformer to “step-down” the power supply. Example II, take the automobile industry, why is it necessary to manufacture small, insignificant parts, different from all other brands of cars. Parts should be “interchangeable.” A Chevy front wheel break pad should be the same as a Ford front wheel break pad. They should only be allowed to change the part design or make it different, when it is “IMPROVED.” Then, when a company makes a better part, throw out the old one, and all autos are fitted with the new and improved one part that fits all. So unless 240v is cheaper to produce, cost efficient to use, it should be converted to 110v. There should be a standard. Some products come with a built-in transformer, with the proper adapter for wall plug; you can plug it into either. Without the transformer, plugging 110v into 240v will fry the appliance.

Answer 3

I am no electrician but I've noticed the 50 cycle 230 volt is much more efficient in Europe for things like toasters, dryers, hair dryers, ect. I'm sure the American 110 volt 60 cycle was a safety consideration. After all, the electric company delivers 220 volt to your fuse box in America and then the fuse box splits that in half. Because energy in Europe costs roughly twice as much there is much more conservation with things like motion-detector lights.

Answer 4

The actual value is 240v. There is no logical reason for the differrence, maybe it's because the Americans are retarded or maybe it's because they want to be "different" (they also try to be different with their driving on the wrong side of the road and having the steering whell on the wrong side of the car).

Answer 5

basic electronics by grob

Power = Voltage x Current

Voltage = Power / Current

Current = Power / Voltage

now try to solve it.
