Water has a high relative permittivity of about 80 at room temperature; because polarity shifts are rapidly transmitted through shifts in orientation of the linked hydrogen bonds.
22.
The imaginary part of the ( frequency-dependent ) relative permittivity is a measure for the ability of a dielectric material to convert electromagnetic field energy into heat.
23.
Because of the smaller relative permittivity and lower dielectric strength of the PEN polymer, PEN film capacitors are physically larger for a given capacitance and rated voltage value.
24.
The width of the strip, the thickness of the substrate and the relative permittivity of the substrate determine the characteristic impedance of the strip which is a transmission line.
25.
Where ? is the permittivity and ? r the relative permittivity of the medium, likewise ? is the permeability and ? r are the relative permmeability of the medium.
26.
Using the certified capacitance, area, thickness, and volume the following relative permittivity was calculated : The average relative permittivity of the four layers = 15, 476.
27.
Using the certified capacitance, area, thickness, and volume the following relative permittivity was calculated : The average relative permittivity of the four layers = 15, 476.
28.
In that case, replace " Q " by " Q " / ?, where ? is the relative permittivity due to these other contributions.
29.
Likewise, relative permittivity is the ratio of the capacitance of a capacitor using that material as a dielectric, compared to a similar capacitor that has vacuum as its dielectric.
30.
Where \ epsilon is the relative permittivity, and \ mu is the relative permeability of the material ( 1 : the glass block, 2 : the metal film ).
