Hence, W = Vq If the battery delivers a small amount of charge dQ at a constant potential V, then the work done is Now, the total work done in delivering a charge of an amount q to the capacitor is given by Therefore the energy stored in a capacitor is given by Substituting
The energy stored in a capacitor is nothing but the electric potential energy and is related to the voltage and charge on the capacitor. If the capacitance of a conductor is C, then it is initially uncharged and it acquires a potential difference V when connected to a battery. If q is the charge on the plate at that time, then

E ( r ) dv A coaxial capacitor consists of two concentric, conducting, cylindrical surfaces, one of radius a and another of radius b.
The energy UC stored in a capacitor is electrostatic potential energy and is thus related to the charge Q and voltage V between the capacitor plates. A charged capacitor stores energy in the electrical field between its plates. As the capacitor is being charged, the electrical field builds up.
The expression in Equation 8.4.2 for the energy stored in a parallel-plate capacitor is generally valid for all types of capacitors. To see this, consider any uncharged capacitor (not necessarily a parallel-plate type). At some instant, we connect it across a battery, giving it a potential difference V = q / C between its plates.
Knowing that the energy stored in a capacitor is UC = Q2 / (2C), we can now find the energy density uE stored in a vacuum between the plates of a charged parallel-plate capacitor. We just have to divide UC by the volume Ad of space between its plates and take into account that for a parallel-plate capacitor, we have E = σ / ϵ0 and C = ϵ0A / d.
