Online calculator to calculate the relative dielectric constant (ฮตr) of a circular capacitor using circle radius, thickness of the dielectric and capacitance values.
Formula:
ฮตr = 1 รท [(0.0885ฯrยฒ/Cd) + 0.0885r/C ร ( In(16ฯr/d) - 1 )]
where,C = capacitance,
r = radius of a circle,
d = dielectric thickness
