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 'Gauss' law seems to imply instantaneous electric field'
Imagine a charged sphere at the origin connected through an open switch to a vertical grounded wire. We wish to find an expression for the horizontal component of the electric field at a distance ##\mathbf{r}## from the sphere as it discharges. By using the Lorenz gauge condition: $$\nabla \cdot \mathbf{A} + \frac{1}{c^2}\frac{\partial \phi}{\partial t}=0\tag{1}$$ we find the following retarded solutions to the Maxwell equations If we assume that...
Maxwell’s equations imply the following wave equation for the electric field $$\nabla^2\mathbf{E}-\frac{1}{c^2}\frac{\partial^2\mathbf{E}}{\partial t^2} = \frac{1}{\varepsilon_0}\nabla\rho+\mu_0\frac{\partial\mathbf J}{\partial t}.\tag{1}$$ I wonder if eqn.##(1)## can be split into the following transverse part $$\nabla^2\mathbf{E}_T-\frac{1}{c^2}\frac{\partial^2\mathbf{E}_T}{\partial t^2} = \mu_0\frac{\partial\mathbf{J}_T}{\partial t}\tag{2}$$ and longitudinal part...
