A capacitor stores energy in an electrical field, while an inductor stores energy in a magnetic field. This affects how they are used in circuits. Capacitors are typically used to filter out noise, while inductors are mainly used to store and release energy. When choosing a component for a circuit, it is important to consider application.
The energy (E) stored in a system can be calculated from the potential difference (V) and the electrical charge (Q) with the following formula: E = 0.5 × Q × V. E: This is the energy stored in the system, typically …
At this time, other capacitors in the capacitor bank will inject a large amount of energy into the faulty capacitor, which may cause damage or even an explosion. Therefore, it is of great significance to set a series protection inductor, which can limit the peak value and the rising rate of the short-circuit current and absorb the discharge …
Energy Density Formula. In the case of electric field or capacitor, the energy density formula is expressed as below: Electrical energy density = permittivity×Electricfieldsquared 2 In the form of equation, UE = 12ε0E2. The energy density formula in case of magnetic field or inductor is as below:
The energy storage inductor in a buck regulator functions as both an energy conversion element and as an output ripple filter. This double duty often saves the cost of an additional output filter, but it complicates the process of finding a good compromise for the value of the inductor. Large values give maximum power output and low output ...

An inductor can be used in a buck regulator to function as an output current ripple filter and an energy conversion element. The dual functionality of the inductor can save the cost of using separate elements. But the inductor''s inductance value must be selected to perform both functions optimally.

Figure 2 Energy stored by a practical inductor. When the current in a practical inductor reaches its steady-state value of Im = E/R, the magnetic field ceases to expand. The voltage across the inductance has dropped to zero, so the power p = vi is also zero. Thus, the energy stored by the inductor increases only while the current is building up ...
Also, for the same occupancy / volume, a capacitor can store more energy than an inductor. But, you could also factor in the method of putting energy into the capacitor or inductor. For instance, if you charged a capacitor from a voltage source, you would immediately lose 50% of the energy (a pulse of "infinite" current would also flow …
