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 ...

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 ...

Among the abundance of components making up electronic circuits, very few are as important as capacitors. These components, taking the form of conductive plates separated by an insulating material ...

Every now and then you need to make your own capacitor. That includes choosing a dielectric for it, the insulating material that goes between the plates. One dielectric material that I use a lot is ...

Dielectrics are of two types: (i) Non-Polar Dielectrics: When the centre of positive charge coincides with the centre of negative charge in a molecule, e.g., Nitrogen, Oxygen, CO 2 etc. (ii) Polar ...

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 ...

Capacitor is a type of passive component which is generally used to store the charge. In capacitors, electrical charge is stored and it produces potential difference across its two plates. There are a ...
