To be able to control and understand the effects of capacitors and inductors, one has to first of all understand how these elements in-teract with other devices in a circuit. Here, we focus on how they interact with resistors and sources.
Stored energy per unit volume: Stored energy per unit volume refers to the amount of energy stored in a given volume of space within an electric field, particularly in the context of capacitors. This concept is crucial for understanding how capacitors store electrical energy and how that energy can be utilized or released in electrical circuits.
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.
If the capacitor is subjected to an AC voltage, the time-averaged energy stored in the capacitor is calculated by substituting the effective voltage as follows. Ecapacitor|average AC = CVC, eff2 2 Average energy stored in a capacitor driven by an AC voltage.
If the inductor is subjected to an AC current, the time-averaged energy stored in the energy is calculated by substituting the effective current as follows: Notice that unlike the energy stored in the resistor, the energy stored in the adiabatic inductor can both increase and decrease. The last component we will consider is the battery.
E = 1/2 cv²: The equation $$e = \frac {1} {2} cv^ {2}$$ represents the energy stored in a capacitor, where 'e' is the energy in joules, 'c' is the capacitance in farads, and 'v' is the voltage across the capacitor in volts. This relationship shows how the energy stored in a capacitor depends on both its capacitance and the voltage applied.
This separation of charge stores electrical potential energy within the capacitor. The energy remains stored until the capacitor is connected to a load, at which point the energy is released, and the capacitor discharges. Capacitance, measured in farads (F), is the capacity of a capacitor to store an electric charge.

As one would suspect, this means that the …
These two distinct energy storage mechanisms are represented in electric circuits by two ideal circuit elements: the ideal capacitor and the ideal inductor, which approximate the behavior of actual discrete capacitors and inductors. They also approximate the bulk properties of capacitance and inductance that are present in any physical system.
Capacitance, measured in farads (F), is the capacity of a capacitor to store an electric charge. It is determined by the surface area of the plates (A), the distance between them (d), and the dielectric constant ( (epsilon)) of the insulating material.
