RMS to Peak Conversion: Magnetic Field Experiment

AI Thread Summary
The discussion centers on the conversion of RMS values to peak values in the context of a magnetic field experiment. Typically, RMS values are multiplied by 1.41 (or √2) to obtain peak values for sinusoidal signals. However, the device in question requires multiplying the RMS values by 2.82 (or 2√2), indicating a different calculation method. This adjustment is attributed to specific experimental conditions and the relationship between average and RMS values in the context of the device's operation. Understanding these factors is crucial for accurate measurements in the experiment.

I know that the RMS values need to be multiplied be 1.41 to get peak values, but now we are doing an experiment with magnetic field, there is a device that produces the magnetic field and the manual says we are supposed to multiply RMS values (which this device shows) by 2.82 to get the peak values. Can you please explain how it got doubled?

It depends specifically on the experiment and some kind of symmetry between the average value and the RMS value that gives you the factor to multiply by.

Note that 1.41 = \sqrt{2} and 2.82 = 2\sqrt{2}[/tex]
 
Thanks, I understand now it's just for sinusoids that 1.41 or \sqrt{2} is the factor.
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
