james has built a parallel plate capacitor of width W, length L, plate distance D, and has filed it with a dielectric material having a relative dielectric constant Er. Assume L >> d and W >> d. The maximum voltage that James can apply to this capacitor is limited by Vmax = Kd, where K is the breakdown strengh of the dielectric. deriven an expression for the maximum energy that can be stored in this capacitor in terms of K and the volume of the dielectric. if James wants to store the maximum energy per unit volume, do the values of L,W and d matter? if yes, expain how they matter. if no, then explain which parameters matter?
