Derive an expression for energy density of a parallel plate capacitor.

In what form of field, is the energy of a capacitor stored? Derive an expression for energy of a parallel plate capacitor.

A. A device to store electrical charge is called a. Transformer b. Capacitor c. Resistor d. Inductor B. What is meant by energy density of a parallel plate capacitor? C. Derive an expression for the energy stored in a parallel plate capacitor. D. What is the area of the plates of a 0.1muF parallel plate air capacitor, given that the separation between the plates is 0.1 mm.

Using the above expression, show that energy density of a parallel plate capacitor is [1/2(epslion_0 E^2)] where .E. is electric field between parallel plates.
