Consider a capacitor with 4 parallel plates and 3 dielectric insulators arranged like this...+I-I+I-
The insulator in the center has an equal amount of + and - charge on each side of it so shouldn't the electric field across this insulator be almost zero? If I constructed this capacitor with the first and last insulators capable of holding 100 volts and this center insulator only capable of holding 10 volts could I actually charge the capacitor to 100 volts without penetrating the center insulator?
