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 ...

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 ...

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 ...
