Question

A capacitor is constructed in the following way: a 1:00m2 layer of conductor, followed by a 0:20mm thick 1:00m2 layer of fused quartz, followed by a 1:00m2 layer of conductor, followed by a 0:40mm thick 1:00m2 layer of pyrex, followed by a 1:00m2 layer of conductor.

(a) Calculate the capacitance of this capacitor.

(b) Calculate the potential across each of your individual capacitors if you apply 5V across the entire capacitor.

(c) Calculate the field inside each capacitor if you apply 5V across the entire capacitor.

(d) If I continually raise the voltage across the capacitor, which dielectric will break down first? At what voltage does this occur?
