If I got a capacitor rated 630 volts and put one aluminum plate on either side. If I then charge the capacitor, the charges will be stored on either side of the polythene dielectric. the charged dielectric will induce charges in the two plates on either side.
(a) If I don't discharge the capacitor but connect the plates on the sides it will discharge/repel the charges similar to the adjacent plates of the capacitor. Do you think the outside plates will release equal to 30% power of capacitor in the middle? Can this be simulated in COMSOL?
