What is the unit of energy density for a parallel plate capacitor?

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

What is meant by energy density of a parallel plate capacitor?

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

(a) Derive an expression for energy density of a parallel plate capacitor. (b) Radius of a spherical conductor is 9 cm. A+4muC charge is given to it. Calculate the capacitance of conductor.

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.
