In Fig. 4 (a) a surface plot of the energy coefficient m from equation (25) vs. ε and p is shown. A value of m > 1/2 is possible for low values of p (p→0) and large values of ε (ε→1).Another plot of m versus ε and p, for α = 0.75, is shown in Fig. 4 (b) where one can clearly see that m > 1/2 is also possible and even in a wider range of ε and p.

4.8: Energy Stored in a Capacitor

Knowing that the energy stored in a capacitor is (U_C = Q^2/(2C)), we can now find the energy density (u_E) stored in a vacuum between the plates of a charged parallel-plate capacitor. We just have to divide (U_C) by the volume Ad of space between its plates and take into account that for a parallel-plate capacitor, we have (E = sigma/epsilon_0) and (C = epsilon_0 A/d).
