The capacity \(C\) of a capacitor
with area \(A\) and distance \(D\) can be calculated from \[C = \epsilon_0 \cdot \epsilon_r \cdot \frac{A}{D}
= 88.5 pF\] with \(\epsilon_0 =
8.854187 \cdot 10^{-12}\) electric constant, \(\epsilon_r = 1\) material property, \(A = 1 \cdot 10^{-4} m^2\), \(D = 1 \cdot 10^{-5}m\)
The electric current \(I\) in a
capacitor circuit with a frequency \(f\) and capacity \(C\) results from \[I = -j \cdot 2 \pi \cdot f \cdot C = -j \cdot
2.781624 \cdot 10^{-8} A\] The simulation result is \(2.781624476936687 \cdot 10^{-08}\) and
thus, the deviation is smaller than \(0.1\%\).
