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 ...

Capacitors connected in parallel, the total capacitance is the sum of the individual capacitors’ capacitances. If two or more are connected in parallel, the effect is that of a single equivalent ...

Portland, Ore. – Using conventional materials-processing technology as a foundation, researchers at the University of California-Davis have developed nanotube-based thin films to build capacitors with ...
