the dielectric strength, n, of a material is the largest electric filed it can be subjected to without breaking down, or in other words, without starting to conduct charge through itself. show that the maximum energy that can be stored in a parallel plate capacitor ( plate area A and plate separation d, filled with dielectric of constant K and strength n) is proportional to the volume of the region between the plates.

1. What is the capacitance of this capacitor?

2. what is the maximum potential difference that can be applied to the plates of this capacitor without causing breakdown?

3. What is the maximum energy Ucmax that can be stored in this capacitor without causing breakdown?

4. Does your answer to Part C show that Ucmax is proportional to the volume of the capacitor?
