Variable capacitors may be useful, but the air gap that provides their capacitance is their greatest weakness. Rather than ...

Of course, we all know that capacitors are conceptually two conductors separated by a dielectric of some sort. But outside of air-variable capacitors you normally don’t see them looking like that. For ...

There was a recent news item regarding a teenager's project to use a super capacitor as a quick-charging energy storage device. The primary claim is that this could be used to fully charge a phone in ...

One of the standard types of components in electronic circuits is capacitors, and often occurring in practical circuits are the complicated combinations of capacitors. When we connect two capacitors ...
