Resistance between parallel wires in an insulator?

AI Thread Summary
The discussion focuses on calculating the insulation resistance between two parallel conductors, specifically copper pins, buried in an insulator like PTFE. The user seeks a formula applicable to this scenario, noting the dimensions of the conductors and their spacing. They mention having found resources for concentric cylinders but not for parallel conductors. There is a question about whether the diffusion equation for heat flow could be relevant to this resistance calculation. The inquiry highlights a gap in available formulas for this specific configuration.

Hi all,

New here...I was wondering if anyone knows a formula to calculate the (insulation) resistance between two parallel conductors buried in an insulator. For example say 2 copper pins of 1mm diameter spaced 2mm apart over a 20mm length in a plastic (ptfe). The numbers/material are not specific to what I want to do just for example purposes.

Any help would be great as I've seen stuff for concentric cylinders but nothing for parallel conductors.

Would it be the same diffusion equation as for heat flow?
 

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...
