Homework Statement



Two parallel plates are connected to a constant electrostatic potential.
Half the space between the plates is filled whit air, one quarter whit a conductor and the fourth quarter whit a dielectric whit realtive permittivity of 80. What is the maximum electric field in the system?


Homework Equations



Between the plates [tex] E = \frac{V}{d} [/tex] V = potential difference and d = distance between plates.

The Attempt at a Solution



Well first I think that the air will "break" first. I do also think that I need to calculate the flux density first, however Im not sure how to procced

It's just two capacitors in series.. one with dielectric and one without (and different dimensions).
