Relative Dielectric Constant Calculator

Posted by Dinesh on

Online calculator to calculate the relative dielectric constant (?r) of a circular capacitor using circle radius, thickness of the dielectric and capacitance values.

Calculate Circular Capacitor Relative Dielectric Constant

Formula:

?r = 1 [(0.0885?r/Cd) + 0.0885r/C ( In(16?r/d) - 1 )]

where,
C = capacitance,
r = radius of a circle,
d = dielectric thickness
