Suppose that a parallel-plate capacitor has a dielectric that breaks down if the electric field exceeds K V/m. Thus, the maximum voltage rating of the capacitor is V max =K d, where d is the separation between the plates. In working Problem P3.33, we find that the maximum energy that can be stored is w max = 1 2 ∈ r ∈ 0 K 2 (Vol) in which Vol is the volume of the dielectric. Given that K=32× 10 5 V/m and that ∈ r =1 (the approximate values for air), find the dimensions of a parallel-plate capacitor having square plates if it is desired to store 1 mJ at a voltage of 1000 V in the least possible volume.

A capacitor is connected to an AC square wave voltage source and a resistor, thus realising the circuit showed in Figure A2 a). The voltage source has a frequency of 3.2 kHz, and the duty cycle is 5%, as showed in Fig A2 b).

Calculate the maximum value of the resistance R such that the voltage across the capacitor Vc reaches the maximum value of 4.5 V (consider 5 time-constants).
