You need alternating current to operate a transformer. (It does not work with DC). Transformers are required to step up and down the voltage which is required to transport electric energy in an economic way. frequency's of 40 to 400 Hz work fairly well for transformers, and the choice with in this range must have been fairly arbitrairly. But one can imagine that the number 60 is inspired minutes of a clock, wher as the number 50 is inspired by the decimal number counting (a half of 100). By the way 60 Hz is slightly more efficient. A US transformer often has a hard life in Europe. For weight saving the frequency of installations in airplanes are historically 400Hz. Transformers can be much smaller this way.
As almost everywhere in Europe, 230-250V, 50Hz
Wealth was determined by gold.
Blood group B has its highest frequency in Northern India and neighboring Central Asia, and its incidence diminishes both towards the west and the east, falling to single digit percentages in Spain. It is believed to have been entirely absent from Native American and Australian Aboriginal populations prior to the arrival of Europeans in those areas. Blood group A is associated with high frequencies in Europe, especially in Scandinavia and Central Europe, although its highest frequencies occur in some Australian Aborigine populations and the Blackfoot Indians of Montana.
Electricity in EuropeThe European version of electricity is generally supplied at 220 volts and a frequency of 50 Hz. Officially it is 230 volts plus or minus 10%. Some localities have 110 volts, but 50 cycles is the standard frequency regardless of the voltage throughout France, Italy, Germany, Britain, Spain, and the rest of Europe. The quantity available depends on the hotel or home where you are staying
'Hz' is the symbol for 'hertz', the SI unit for frequency -equivalent to a 'cycle per second'. The frequency of your supply is 50 Hz in Europe, or 60 Hz in North America.The 'watt' is the SI unit for power, which is the rate at which your electrical appliances use energy.

RF Code first began offering products in the 303MHz range (US & Japan) and later in the 433MHz range (US & Europe). These signal frequencies are limited, low-power, unlicensed ranges in the ISM (Industrial, Scientific and Medical) portion of the UHF band. RF Code began offering 433MHz products because of acceptance of this frequency in Europe. 433MHz is also the frequency which offers optimal performance in crowded environments such as offices, data centers, and hospitals. Generally, radio signals at lower frequencies travel farther than those at higher frequencies. Lower frequencies also benefit more from the effects of reflection and refraction which makes them more suitable for applications in crowded environments. For example, the 433MHz wavelength is approximately 69 cm vs. 10 cm for 2.4GHz. The larger wavelength of the 433MHz signal allows it to diffract around obstructions that might be found in a typical, crowded operating environment such as an office or warehouse. At frequencies of 2.4GHz and above, the signal is susceptible to obstructions, creating blind spots (areas of no coverage). Higher frequencies also require more power.
Bodies of water during the medieval time period in Europe determined transportation. These bodies of water also determined trade routes.

One critical relationship between line frequency and magnetic devices is efficiency. The physics of electric circuits tells us that AC magnetic devices increase in efficiency as line frequency increases. Another physical characteristic to keep in mind is that current flow in a conductor tends to be closer to the surface of the conductor as frequency increases. So as the frequency goes up, solid conductors begin to resemble hollow pipes as the electrons making up the current flow migrate to the outer surfaces of the conductors. At these higher frequencies, the energy of the electrons has a tendency to actually leave the surface of the conductor. A common example of this principle in action is radio transmission. As the frequencies get higher, all of the energy can be made to leave the conductor in a form of energy called radio waves. This also helps explain why overhead power lines tend to interfere with radio reception (the annoying 60-cycle hum). What you are hearing is energy loss from the power lines becoming a radio wave that is intercepted by the radio receiver. Consequently, the designers of electrical devices must strike a balance: the desire to use higher frequencies to improve the efficiency of converting electrical power to mechanical work and the need for lower frequencies to keep power from escaping the conductor as radio waves. So the evolution of 50 and 60 hertz systems developed as a result of this need for balance, with additional influences coming from politics and geographic considerations. North America and other regions struck the balance at 60 hertz, while Europe settled on 50 hertz.
It will work in most countries in Europe. However, it will not work in the United States because the US uses different frequencies from Europe.
European countries have different frequencies of power from the United States, and also from each other. You will definitely need a travel adapter for all of your plug-in electronics, and you need to make sure the plugs are able to accept the altered frequency. Look to related links for more information.
Europeans have a very high standard of living, especially in Western Europe. In fact, Western Europe has the highest standard of living in the world.
The electrical switches used in Europe contain a widely spaced, two-pronged interface. Universal adapters can be found in a variety or retail stores such as Walmart or Staples.
The GPRS is running at 800Mhz in Europe while In US, it is running at 1900Mhz.
50 Hz.AnswerSupply frequency depends on where you live. In North America and parts of Japan, for example, the frequency is 60 Hz. On the other hand, in Europe and in much of the other parts of the world, the frequency is 50 Hz.
230 for Europe
In North America 60 Hertz. Europe 50 Hertz.
In North America it is 60 Hertz. In Europe and the UK it is 50 Hertz.
Europe is the world's second smallest continent. This is determined by surface area. It covers about 3,930,000 sq. miles. It is two percent of the Earth's surface.
The frequency of any alternating current (ac) electrical supply always depends on the frequency at which the supply has been generated.That is true no matter whether it was generated at a power station, for use in a home or factory, or in a dc-to-ac power inverter unit, for use in, say, a vehicle or boat.Power stations in USA, Canada and other countries generate ac at 60 Hz.Power stations in countries in Europe and other world areas generate ac at 50 Hz."Hz" is short for "hertz" which is the name used internationally for "one cycle per second".
The outlets are the same, only the voltage is different.
In North America, it is 60 Hertz, and in Europe it is 50 hertz.
