At 400Hz all electrical equipment like alternators, Transformers and electric motors become smaller to supply the same power than 50 or 60Hz equipment, they are using Bosh 90 amp auto alternators same size as BMW and Mercedes with some internal modifications that is capable of up to 8.4 Kw and 70 Volt 3 phase that is then inverted to 220 Volt with a transformer

Why 400 HZ for air crafts?
400 Hz is used in aircraft because it allows transformers to be much smaller than if the frequency was lower. A 50 Hz transformer would weight eight times as much. But 400 Hz is not useful for transmitting over distances of more than a few hundred metres because of power losses.
How do the wavelength of each of these Sound waves compare An instrument plays a pitch of 266 Hz. Another identical instrument plays a pitch of 400 Hz.?
The wavelength of a sound wave is inversely related to its frequency. Since the speed of sound in air is approximately constant, a lower frequency (like 266 Hz) corresponds to a longer wavelength, while a higher frequency (400 Hz) has a shorter wavelength. Specifically, the wavelength of the 266 Hz sound wave will be longer than that of the 400 Hz sound wave.
What is the range of frequence for normal speech?
400 Hz to about 5000 Hz
How many Hz are in 2.4 GHz?
2 400 000 000 Hz
What is the frequency of ultra violet?
400 HZ
Reason for choosing 400 Hz as the number of cycles in AC?
Aircraft use 400 Hz for their power supplies because it allows them to use smaller and lighter components.
What is the wavelength of 400Hz?
The wavelength of a 400 Hz wave in air is approximately 0.85 meters. This can be calculated using the formula: wavelength = speed of sound / frequency.
When 50 Hz frequency is given to a 400 Hz transformer. Will it work?
A 400 Hz transformer is designed to operate optimally at that frequency and may not function correctly at 50 Hz. When supplied with 50 Hz, the transformer could experience issues such as overheating, increased magnetic losses, and reduced efficiency due to the lower frequency not matching its design specifications. Additionally, the core might saturate, leading to potential damage. Therefore, while it may physically operate, it is not advisable to use a 400 Hz transformer at 50 Hz.
What is the second octave of 200 Hz?
The second octave of 200 Hz is 400 Hz. In music theory, each octave represents a doubling of the frequency of the previous octave.
Why 50hz only not other frequencies can use?
There are other frequencies, such as 60 Hz, 25 Hz, and 400 Hz in common use. Please restate the question - it does not make sense.
What frequency does air vibrate?
Air vibrates at frequencies between 20 Hz and 20,000 Hz, which corresponds to the range of human hearing. Below 20 Hz is considered infrasound, and above 20,000 Hz is considered ultrasound.
If a note has a frequency of 400 hz how many sound waves per second?
If a note has a frequency of 400 Hz, it means that there are 400 sound waves produced in one second. The frequency of a sound wave is the number of complete waves that pass a point in one second.
