In the way you originally proposed the problem, you have two spheres connected to the plates. In total, yes, you have two conductors with different charges, and the charge distribution will be complex. But the charge should be distributed in such a manner that, on the surface of the plates, the...

IMO, despite that, the capacitor plates themselves should have equal and opposite charges to prevent the electric field from penetrating the conductor. If you model the capacitor as two parallel plates, the charge is induced in their surfaces to block the other's field.

Hey berkeman, thanks for the reply In my masters I'm exclusively using VASP to simulate III-V alloys and python to develop pre and post-processing tools. In my bachelor degree I use SPICE for circuit simulation and MATLAB for control/ telecommunications/ general purpose programming. Sadly my...

Hi friends, I'm a brazilian Electronics Engineering undergrad student, going to graduate in 3 semesters. I'm also in the first semester of my Masters in Atomic and Molecular Physics, focused on ab initio simulation of semiconductor crystals (VASP). My main interest is to work in industry in...

Homework Statement The electric flux density in free space produced by an oscillating electric charge placed at the origin is given by \vec{D}=\hat{r}\frac{10^{-9}}{4\pi r^2}cos(wt-\beta r), \ \ where \ \beta=w \sqrt{\mu_0 \epsilon_0} Find the time-average charge that produces this electric...
