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.
Working Principle of an Electronic Ballast. The electronic ballast accepts a 50-60 Hz supply, converting AC voltage to DC. This DC voltage is then filtered using a capacitor arrangement before being supplied to a high-frequency oscillation stage, which typically outputs a square wave between 20 kHz and 80 kHz.

Working of a Capacitor. Basically what is happening inside a capacitor is that the insulator between those plates is undergoing a process called ''dielectric breakdown'', meaning the insulator can no longer insulate since the voltage across the insulator is too high for it to be able to remain an insulator. The underlying physics is somewhat off scope, but all you need to …
