Dielectric reluctance

Dielectric reluctance is the scalar value, which is equal to the relation of the voltage on the part of a passive dielectric circuit and the electric induction flux in this part or to relation their amplitude values for the sinusoidal voltage and flux of electric induction.

Weighing the right way

Dielectric reluctance [1-3] is measuring in units – [1/F] and determining by the formula:

If the energy loss in a dielectric of the dielectric circuit are absent, then existence of the dielectric reluctance (resistance for an electric induction flux) not causes to a consumption of energy, though here the relationship, which is formality similar to Ohm's Law for an electric circuit, and has a place. So for a uniform path of a dielectric circuit the dielectric reluctance z_ε is determining by the expression:

where l , S is the length and cross-section of the part of a dielectric circuit; εε₀ is the dielectric permeability.
