What formula would be used to convert at current transformer rating at 60Hz to 25Hz?
I don't understand your question. Are you asking how to convert from 60hz to 25hz using a transformer? That cannot be done. Frequency in = frequency out.
What is the wavelength of a 25hz sine wave?
The wavelength of a 25Hz sine wave can be calculated using the formula: wavelength = speed of sound / frequency. Assuming the speed of sound is approximately 343 meters per second, the wavelength of a 25Hz sine wave would be around 13.72 meters.
Whether the sound produced by a seconds pendulum is infrasonic or ultrasonic?
Infrasonic denotes any sound that is at a frequency below the human capability of hearing, this is around 5-25Hz. Ultrasonic on the other hand is, conversely, a frequency that is above the human hearing range (over 20,000Hz).
What is a perfect harmonic of a 25Hz tone?
50, 75, 100
What is better 25Hz-20kHz or 20Hz-20Khz for headphones?
For headphones, a frequency range of 20Hz-20kHz is generally considered better than 25Hz-20kHz. This is because the lower limit of 20Hz allows for the reproduction of deep bass sounds, which can enhance the overall listening experience, especially in music genres that rely on low frequencies. The human hearing range typically spans from about 20Hz to 20kHz, so a wider range can provide a more accurate and immersive sound representation.
What is the Approximate range of audible frequencies for most humans?
HIGHEST AUDIBLE FREQUENCY IS 25Hz..WHILE THE LOWEST AUDIBLE FREQUENCY IS 15Hz
Given 220 volts 15 amperes 700 rpm and 0.8 ohms what speed will it run if a resistance is connected in series with supply voltage assume the motor is taking the same current?
Most probably, it won't even run or it will run for a while and then burn out, a motor that run 700rpm is an 8 pole induction motor, the only way to get it to run slower or faster is to change the supply frequency, say you want it to run at 350 rpm you have to change the supply frequency from 50Hz to 25Hz
What is the purpose of DSL filters on phone jacks in your house?
Regular telephone conversations use the lower section of the lines frequency range. depending on the company, voice is carried between 25hz and 3500hz. The DSL signal is carried from 10000hz to approx 3.5mhz, the 10000hz part is in the audible range, so without a filter you will hear a hiss or static on the telephone when you try to use it. Not only is this annoying but it interferes with the signal and will make your DSL go slower. Filters are very important.
What is the correct frequency for a 1080p blu ray player?
The television frame or field frequency will vary according to the content. It is the content that defines the frequency and not the hardware it plays on. In Europe, the field rate for 1080i signals is 50Hz with the frame rate at 25Hz. For 1080p, the frame and field rate are normally both 50Hz In North America, the rates are 30Hz and 60Hz respectively. There are some other rates that might rarely be seen. Commercial film production uses a frame rate of 24Hz and sometimes video conversions will capture at a 24Hz frame rate. For an HD capture, the full description will be 1080p, 24. Similarly, in Europe, film is often converted to video at 25 frames per second by increasing the playback speed of the film. The resulting video can then be 1080p, 25. Many Bluray and DVD players will simply output the video at the frame rate that is stored on disc rather than converting it to different rates.
Is 20 hz audible?
Yes, but barely. The sensitivity of human hearing falls rapidly at very low frequencies so there is no easily defined cut-off point. It becomes increasingly difficult to distinguish the pitch of pure tones as their frequency falls below about below 25Hz, and the sensation becomes more one of feeling rather than hearing; along those lines most people can "hear" down to 20Hz or lower.
What is the difference between PAL and NTSC?
PAL and NTSC are color encoding formats. NTSC is the format used in North America and PAL is used in Europe. Most other countries use one or the other. NTSC is normally used at a frame rate of 29.97Hz with 480 lines used for the image while PAL is normally 25Hz and uses 576 lines. The frame rate and line count are actually independent of the color encoding format used so there are instances where US frame rates and line counts can be used with PAL color encoding and vice versa. PAL and NTSC are similar formats but not interchangeable. Many modern televisions will now handle PAL and NTSC but that is not always the case.
What is the best hz rating on tv?
The native frequency of a television signal is 25Hz, 30Hz, 50 Hz or 60Hz, that is, an image refresh 25, 30, 50 or 60 times every second. Any television that features a faster refresh such as 100, 120, 200, 240 Hz is using a video processor to generate intermediate images to refresh the screen faster than the native signal would do. Some of the processors do a reasonable job while others don't show much improvement. Some will say that the processing actually makes for a lower quality image rather than higher. Before investing money in a television that offers high refresh rates, make sure you get to look at the image and decide for yourself whether it improves the image or not.
