Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than deal with the poor dielectric properties of air, some high-end variable ...

This file type includes high resolution graphics and schematics. Capacitors often are connected in parallel in power electronics to decrease high-frequency ripples, current stress, decrease power ...

Ideal capacitors only exist in textbooks. Every real-world capacitor has additional complexity arising from its physical structure. Two plates separated by a dielectric layer are in series with wire ...

If you think about dielectric properties at all, it is probably in the context of school physics experiments on charge storage, or perhaps the way in which the choice of dielectric materials ...
