    Curves Resonance
AI Thread Summary
The discussion revolves around reproducing resonance curves for a driven RLC circuit using specified values for resistance, inductance, and capacitance. An initial attempt yielded a flatter curve than expected, prompting questions about the accuracy of the resistance values. It was suggested that the correct curves might be achieved with different resistance values while keeping the original inductance and capacitance. Ultimately, the original poster acknowledged that their curves were correct and expressed a desire to retain the thread for future reference. The conversation highlights common challenges in plotting RLC resonant curves and the importance of precise component values.

TL;DR Summary
I am trying to reproduce the resonance curves at page 925 of "Physics, 10th edition" by Halliday et al.
It seems to me that there is something wrong in the values for the parameters

I tried to reproduce these curves. The values for the resistance are shown in the graph. The other values are ##L=100 {\rm \mu H}## and ##C=100 {\rm pF}##.
Using those values I get a much flatter curve, where the value at 0,9 is roughly 83% of the value at 1,00.
Am I missing something?

It seems to me that curves such as those in the figure are obtained with ##R = 0.2 {\Omega}##, ##R = 0.6 {\Omega}## and ##R = 2.0 {\Omega}##. Probably it is possible to obtain the same curves keeping the given values of the resistance and changing ##L## and ##C##.

Thank you for any insight
Francesco

sorry my bad. The curves are correct. Forget about it.
I tried to see if I could remove this post, but did not find a way.
 
No need to remove your thread. It will be interesting reading for users in the future searching for help on RLC resonant curve plots. :smile:

I will fix the typo in your ##C## value though. :wink:
 
Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
