Recalling from circuit element definitions, it was determined that resistors just dissipate energy as heat, but inductors and capacitors store energy. The net energy storage of these elements over one cycle was zero. This makes these elements to be categorized as passive elements.
The relation of the voltage and current of energy-storing elements is expressed by differential and integral equations. Therefore, each energy-storing element has the potential of increasing the order of a differential equation written for a circuit.
The two energy storage mechanical elements can have initial conditions that need to be taken into account in the analysis. A mass can have an initial velocity, which will clearly produce a force, and a spring can have a nonzero rest length, which also produces a force.
The energy stored in the state of a capacitor or inductor should be calculable by integrating the power absorbed by the device. Suppose we want to know the energy stored in an inductor in a given state.
The ubiquitous capacitor is a key energy storage element in electronic systems but it turns out that there are many subtleties associated with capacitor design and operation. As an energy storage element, it is important that the capacitor retain most of the stored energy for a specified period of time.
Both groups converters consist of multiple energy-storage elements: two elements, three elements, or four elements. These energy-storage elements are passive parts: inductors and capacitors. They can be connected in series or parallel in various methods. In full statistics, the circuits of the multiple energy-storage elements converters are:
Energy Storage Element
Piezoelectric crystal produces low power, so a low power electronic converter is required to transfer energy from the piezoelectric transducer to energy storage devices. The most common electrical energy storage elements are capacitors, supercapacitors and rechargeable batteries such as lithium-ion batteries [131–136].

What are Resistors
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. This means that they don''t generate power but only consume it. Resistors are normally added to circuits where they complement active components like op-amps, microcontrollers and other integrated circuits. Resistors ...
