Dielectric reluctance

From Wikipedia, the free encyclopedia

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.

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

z_\epsilon = \frac{U}{Q} = \frac{U_m}{Q_m}

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 zε is determining by the expression:

z_\epsilon = \frac{1}{\epsilon \epsilon_0}\frac{l}{S}

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