Dielectric complex reluctance
Encyclopedia
Dielectric complex reluctance is a scalar measurement of a passive dielectric circuit (or element within that circuit) dependent on sinusoidal voltage
Voltage
Voltage, otherwise known as electrical potential difference or electric tension is the difference in electric potential between two points — or the difference in electric potential energy per unit charge between two points...

 and sinusoidal electric induction flux, and this is determined by deriving the ratio of their complex effective amplitudes. The units of dielectric complex reluctance are (inverse Farads - see Daraf

The "lossless" dielectric reluctance
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 [Ref...

, lowercase z epsilon, is equal to the absolute value (modulus) of the dielectric complex reluctance. The argument distinguishing the "lossy" dielectric complex reluctance from the "lossless" dielectric reluctance is equal to the natural number raised to a power equal to:


Where:
  • is the imaginary number
  • is the phase of voltage
  • is the phase of electric induction flux
  • is the phase difference


The "lossy" dielectric complex reluctance represents a dielectric circuit element's resistance to not only electric induction flux but also to changes in electric induction flux. When applied to harmonic regimes, this formality is similar to Ohm's Law
Ohm's law
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points...

 in ideal AC circuits. In dielectric circuits, a dielectric material has a dielectric complex reluctance equal to:


Where:
  • is the length of the circuit element
  • is the cross-section of the circuit element
  • is the complex dielectric permeability

    A dielectric is an electrical insulator that can be polarized by an applied electric field. When a dielectric is placed in an electric field, electric charges do not flow through the material, as in a conductor, but only slightly shift from their average equilibrium positions causing dielectric...
