AI Thread Summary
The discussion revolves around calculating the capacitance between two points on three concentric shells with radii a, b, and c. Participants suggest treating the shells as two capacitors in series for simplification. There is a request for a more fundamental approach using the definition of capacitance, C = Q/V. However, the thread was closed due to a reminder that such schoolwork problems should be posted in the appropriate forums with demonstrated effort. The user is advised to re-post their question in the Schoolwork forums for further assistance.

A friend of mine sent me this problem about finding the capacitance.
We have three concentric shells of radius a, b, c. And we've to find the capacitance between x and y.

I need help.

Thank you

Among many ways, you could treat it as two capacitors (a,b ---b,c) in series. What is the capacitance of two concentric shells?

I would love to get a hint to do it any other way. Something that is more basic, like by using just the starting definition of C=Q/ V.
Thank you for your reply :)

You've been at PF long enough to know that any schoolwork-type problem like this needs to be posted in the Schoolwork forums, and you need to show your best efforts to work on the problem. This thread is now closed. Please re-post in the Schoolwork forums. Thank you.

Thread 'Maxwell stress tensor'

This is from Griffiths' Electrodynamics, 3rd edition, page 352. I am trying to calculate the divergence of the Maxwell stress tensor. The tensor is given as ##T_{ij} =\epsilon_0 (E_iE_j-\frac 1 2 \delta_{ij} E^2)+\frac 1 {\mu_0}(B_iB_j-\frac 1 2 \delta_{ij} B^2)##. To make things easier, I just want to focus on the part with the electrical field, i.e. I want to find the divergence of ##E_{ij}=E_iE_j-\frac 1 2 \delta_{ij}E^2##. In matrix form, this tensor should look like this...

Thread 'Applying the Gauss (1835) formula for force between 2 parallel DC currents'

Please can anyone either:- (1) point me to a derivation of the perpendicular force (Fy) between two very long parallel wires carrying steady currents utilising the formula of Gauss for the force F along the line r between 2 charges? Or alternatively (2) point out where I have gone wrong in my method? I am having problems with calculating the direction and magnitude of the force as expected from modern (Biot-Savart-Maxwell-Lorentz) formula. Here is my method and results so far:- This...
