19.7 Energy Stored in Capacitors – College Physics: OpenStax
Energy stored in a capacitor is electrical potential energy, and it is thus related to the charge Q Q and voltage V V on the capacitor. We must be careful when applying the equation for electrical potential energy ΔPE = qΔV Δ PE = q Δ V to a capacitor. Remember that ΔPE Δ PE is the potential energy of a charge q q going through a voltage ΔV Δ V.

4.8: Energy Stored in a Capacitor
The expression in Equation 4.8.2 4.8.2 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 V = q / C between its plates.
How do I know the maximum voltage that a capacitor releases?
Capacitors store energy. The voltage depends upon the amount of charge and the size of the capacitor. (Q = CV, Energy stored = 0.5CV^2). If you connect a resistor across the terminals of a charged capacitor an initial current (= V/R) will flow but this will rapidly fall towards zero as the capacitor is discharged. ...

Capacitors article (article) | Capacitors | Khan Academy
Capacitors store energy by holding apart pairs of opposite charges. Since a positive charge and a negative charge attract each other and naturally want to come together, when they are held a fixed distance apart (for example, by a gap of insulating material such as air), their mutual attraction stores potential energy that is released if they are re-united.

Energy Stored on a Capacitor
The energy stored on a capacitor can be expressed in terms of the work done by the battery. Voltage represents energy per unit charge, so the work to move a charge element dq from the negative plate to the positive plate is equal to V dq, where V is the voltage on the capacitor. The voltage V is proportional to the amount of charge which is ...
