Inverse prediction of capacitor multiphysics dynamic parameters …
We demonstrate inverse prediction on the electrostatics field of an air-filled capacitor dataset where the structural change is affected by a dynamic parameter to the boundary condition. Using recent AI such as deep generative model, we outperformed best baseline on inverse prediction both visually and in terms of quantitative measure.

Characteristics of Capacitor: Fundamental Aspects
where ε is the permittivity of medium, ε 0 is free space permittivity (= 8.854 × 10 −12 F/m) and k is the relative permittivity of the dielectric material inserted between the two plates (k = 1 for free space, k ≈ 1 for air and k > 1 for other natural materials).. From (), it can be inferred that the capacitor basically depends on the dimensions of the structure …

This common power quality problem is usually caused by weather and utility equipment problems, which normally lead to system faults on the transmission or distribution system. For example, a fault on a parallel feeder circuit will result in a voltage drop at the substation bus that affects all the other feeders until the fault is cleared.

18.5 Capacitors and Dielectrics
For a given capacitor, the ratio of the charge stored in the capacitor to the voltage difference between the plates of the capacitor always remains the same. Capacitance is determined by the geometry of the capacitor and the materials that it is made from. For a parallel-plate capacitor with nothing between its plates, the capacitance is given by
Capacitors — Collection of Solved Problems
Charges on capacitors in series are equal to each other and in this case also equal to the total charge. Therefore the charge on the third capacitor is equal to the total charge. If we know the charge, we can evaluate the voltage on the third capacitor. Voltages on both capacitors connected in parallel are the same.
