How to Calculate the Energy Stored in a Capacitor? 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.
How to Calculate the Energy Stored in Capacitor? Work has to be done to transfer charges onto a conductor against the force of repulsion from the already existing charges on it. This work done to charge from one plate to the other is stored as the potential energy of the electric field of the conductor. C = Q/V

Voltage is not the same as energy. Voltage is the energy per unit charge. Thus, a motorcycle battery and a car battery can both have the same voltage (more precisely, the same potential difference between battery terminals), yet one stores much more energy than the other because (Delta U = qDelta V).
Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Q and voltage V on the capacitor. We must be careful when applying the equation for electrical potential energy ΔPE = qΔV to a capacitor.Remember that ΔPE is the potential energy of a charge q going through a voltage ΔV.But the capacitor starts with zero voltage and gradually …

When a free positive charge q is accelerated by an electric field, it is given kinetic energy (Figure (PageIndex{1})). The process is analogous to an object being accelerated by a gravitational field, as if the charge were going down an electrical hill where its electric potential energy is converted into kinetic energy, although of course the sources of the forces are very different.
$begingroup$ @Lehs, in above theories, electromagnetic energy is not a function of the total electromagnetic field. It is zero for one lone particle, because there is no work needed to form it - it has no parts. But bringing two charged particles close to each other does take some work and so the net electromagnetic energy of such a system is positive.

Energy stored in an electric field - Means the Potential Energy (electric) in that space. You do not even need to know volume for energy stored in electric field. It has three equations. PE = (1/2) C[V(net)^2] where C is capacity and V is ''electric potential''. I am sure you can find the other two online.
