Capacitor #1 has a dielectric of hard rubber between its parallel plated and capacitor #2 has a dielectric of mica between its parallel plates (all plates are equal in size). Both were each hooked up to a D.C. source of 15 volts and it was found that, after a long time, both exhibited to have the same amount of charge on them. For this to occur what is the ratio of the dielectric thickness of capacitor #1 compared to that of capacitor #2?
