This calculator finds the total capacitance of a circular parallel plate capacitor from radius, εr and thickness using the formula below.
The total capacitance of a circular parallel plate capacitor including edge effect, can be calculated using the following equation which is derived from Kirchhoff's equation for a circular capacitor.
r is the Radius in mm
εr is the Relative Dielectric Constant
d is the Dielectric thickness in mm
d << r
The calculator can be used to check results obtained with the Accurate Method for Measuring Relative Dielectric Constant of a PCB Using a Vector Network Analyser
