Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

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 ...

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 ...

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 ...

Situation: You’re an IT person new to radio broadcast engineering and are given the keys to an AM transmitter site. The manager says to go out and get familiar with the equipment. The site reminds you ...

As we have seen in part I and part II of this series [1], there are no inherent wear-out mechanisms in ceramic capacitors. And yes, as covered in part II, the high dielectric Class 2 capacitors (X7R) ...

So far our discussion summarizes the fact that in practical electronic systems a combination of different DC-DC converter topologies are used to achieve the overall efficiency, noise minimization, ...

Troubleshooting single-phase compressors requires a technician to have a proficient understanding of capacitors. The run capacitor is one of two types of capacitors that could be found on single-phase ...
