LC natural response (article) | Khan Academy
The amount of q is set by the product of the initial voltage on the capacitor and the value of the capacitor, q = C v . q does not change during the natural response. Starting out, all the charge is sitting still on the capacitor. Now we release the circuit by closing the switch to let it do its "natural" thing. The inductor starts with 0 current.

For high-energy storage with capacitors in series, some safety considerations must be applied to ensure one capacitor failing and leaking current does not apply too much voltage to the other series capacitors. They can also be used in charge pump circuits as the energy storage element in the generation of higher voltages than the input

Inductor is a pasive element designed to store energy in its magnetic field. Any conductor of electric current has inductive properties and may be regarded as an inductor. To enhance the inductive effect, a practical inductor is usually formed into a cylindrical coil with many turns of conducting wire. Figure 5.10.

8.4: Energy Stored in a Capacitor
The expression in Equation 8.4.2 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 V = q / C between its plates.

How does a capacitor store energy? Energy in Electric Field
A: The energy stored in a capacitor is half the product of the capacitance and the square of the voltage, as given by the formula E = ½CV². This is because the energy stored is proportional to the work done to charge the capacitor, which is equal to half the product of the charge and voltage.
