Basics of air capacitors its working principle advantages and uses
An air capacitor is a capacitor that uses air as a dielectric, and this capacitor can be designed in fixed or variable capacitance form. The fixed capacitance type is not often used because there are different types of fixed capacitors with much better characteristics than it, so the variable capacitance form is more frequently used due to its simple construction.
