Mathematically, energy stored in an inductor is expressed as. Where w is the energy stored in the inductor, L is the inductance and i is the current passing through the inductor. Ideal inductors have a noteworthy characteristic - they do not dissipate energy. This trait allows the energy stored within them to be harnessed at a later point in time.
Equation (11) relies only on the value and the first-order derivative of permittivity of individual. oscillators at a specific frequency. If the permittivity and its first-order derivative can be described by. a few oscillators in a spectral range with good accuracy, then the energy density can be calculated.

Something that confuses people when they first start studying electronics is that they try to calculate the power dissipated in a capacitor and inductor. With *ideal*, or perfect, capacitors and inductors, they''re energy storage devices and don''t dissipate any power.
Even an ideal inductor has capacitances associated with it and you will see 1/2.L.i^2 energy redistrubted into 1/2.C.V^2 energy. If there is little or no resistance you will see oscillations as energy is dissipated over longer than a resonance cycle - in the form of electromagnetic radiation if no other means exists.
