    Density Resistance
AI Thread Summary
Resistance can be conceptualized as an obstruction to current flow, akin to how the refractive index affects light. However, the notion of resistance as an electrical density of materials is challenged by established models in solid-state physics, particularly the Drude model. This model provides a foundational understanding of electrical transport and emphasizes the role of electron mobility rather than density. The discussion highlights the importance of relying on established scientific principles to accurately describe electrical resistance. Ultimately, while the analogy to light refraction is interesting, it does not align with the complexities of electrical behavior in materials.

Could resistance be seen as an electrical density of the material?
More the resistance more the obstruction offered to the flow of current just as the refractive index obstructs the flow of light through the medium.

No. You need to pick up a solid state physics text and look at the simplest model - the Drude model - of electrical transport.
 

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...
