Similarly, for a point charge $-3.2,rm mu C$, we can calculate its magnitude and direction of electric field using the same formula above: begin{align*} E&=kfrac{q}{d^2} &=frac{(9times 10^9)(3.2times 10^{-6})}{(0.02)^2} &=72times 10^6,rm N/C end{align*} Since this charge is negative, its electric field is directed …
Thus the energy stored in the capacitor is (frac{1}{2}epsilon E^2). The volume of the dielectric (insulating) material between the plates is (Ad), and therefore we find the following expression for the energy stored per unit volume in a dielectric material in which there is an electric field: [dfrac{1}{2}epsilon E^2 ]
