Air Capacitor : Construction, Working, Permittivity & Its …
Air capacitors have a small capacitance value that ranges from 100 pF – 1 nF whereas the operating voltage ranges from 10 to 1000V. The breakdown voltage of dielectric is less so electrical breakdown will change within capacitor so this can lead to the defective

Note also that the dielectric constant for air is very close to 1, so that air-filled capacitors act much like those with vacuum between their plates except that the air can become conductive if the electric field strength becomes too great. (Recall that E = V / d E = V / d size 12{E=V/d} {} for a parallel plate capacitor.) ...

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 …
