What role do hertz play in electrical transformers?
Q. Does more hertz mean more volts with less amp loss? What what what? Be specific and try not to dumb it down a lot I know a decent part of electricity.

A. Hertz is the number of cycles per second. In North America, electricity is generated at 60 Hz - that means the electrons move forward, then back again, 60 times in one second. In the UK, it's 50 Hz - 50 times in one second. The voltage still hits the same peak. In a resistive load, the current reaches the same peak too. If you have a capacitive load, the higher the frequency in Hz, the more current you will have at the same peak voltage. If you have an inductive load, the higher the frequency in Hz, the less current you will have at the same peak voltage.

How do I change my screen refresh rate above 75 hertz?
Q. I have asperger's syndrome and I have an added sensitivity to light and I can detect the screen flickering at 75 hertz... This seems to be the highest so far, however, I've heard some people have managed to get the refresh rate up to 125 hertz.
Asked by Lily - Wed May 5 00:57:06 2010 - - 4 Answers - 0 Comments
A. You may have to lower the display resolution first. Doing so should let you use 85 Hz or higher, as the lower resolution frees up some bandwidth.

How do I know how many hertz my box is tuned to?
Q. Yeah I was wondering what my speaker box is tuned to.I know that it is 3.8 cubic ft but I never could figure it out to see about what exact hertz it is tuned to.I thinking it is around 32-34Hz because any sub I put in it, it picks up all the low notes no matter what they are.If anyone knows please tell me.Thanks

What can i use to find the frequency of a musical note in hertz?
Q. I am doing a science project, and i need some device that will tell me the frequency of a note in hertz I need something inexpensive that can at least help me determine the frequency of a note.

A. Well...there are devices known as frequency counters...some are for radio frequencies, some may have a microphone... You could also use an oscilloscope...some digital ones will do a frequency measurement. Alternatively you can use the scope to measure the time between peaks and convert that time to frequency with 1/t calculation. If you have a microphone and a sound card... with the right software you could sample the sound and do an FFT (fast Fourier Transform) to get a frequency measurement... If you have a set of tuning forks... you could use those until you found one that sounded like the musical note... if you hear a beat frequency... then you can measure the number of beats per second (by counting for a minute say) and use the… [cont.]

What are the hertz of brainwaves?
Q. I heard that brainwaves run around 13 and some other number of hertz. What is the level of brainwaves and how does living in a modern world affect such behavior?

A. Delta - up to 3hz Theta - 3 to 8hz Alpha - 8 to 12hz Beta - 12 to 30hz Gamme - 26 to 100hz Anything above 26hz is rarely an actual brain wave; it's usually an artifact reading and can only be read via corticoelectroencephalogr aphy (say that three times real fast; means direct contact with the cerebral cortex).

A. When you specify an AC voltage without any qualifiers (like peak or peak-peak), it is usually assumed to be the RMS voltage. In that case the power is 240*240/50 or 1152 watts.

A. Hertz = cycles per second. Anything that happens with a cyclic rate can be measured in hertz, the frequency of a signal, the speed of an engine, etc. The 50 Hz or 60 Hz frame rate was originally due to the frequency of the power mains in the country where the TV set was used. This was an easy way of keeping things on frequency. Modern TV systems don't depend on such things anymore. There are many different types of cables. RF cables carry "Radio Frequency" signals.
