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.

Which blood group has highest frequency?

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.

What is the electrical current in Europe?

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

What is the difference between Hz and watts?

'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.

Why 433 Mhz range selected for RF transmitter and receiver?

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.

Why the 60 hertz is chosen?

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.

What adapter do you get for your electronics for 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.

What is the frequency of a 440 volt electrical supply?

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".
