Dielectric reluctance
Dielectric reluctance is a scalar measurement of a passive dielectric circuit dependent on voltage and electric induction flux, and this is determined by deriving the ratio of their amplitudes. The units of dielectric reluctance are F−1 .
As seen above, dielectric reluctance is represented as lowercase z epsilon.
For a dielectric in a dielectric circuit to have no energy losses, the imaginary part of its dielectric reluctance is zero. This constitutes a lossless "resistance" to electric induction flux, and is therefore real, not complex. This formality is similar to Ohm's law for a resistive circuit. In dielectric circuits, a dielectric material has a "lossless" dielectric reluctance equal to:
Where:
- is the circuit length
- is the cross-section of the circuit element
- is the dielectric permeability
