There is one small problem in my understanding of polarized capacitors.
The thing is that when using polarized capacitor, you should apply positive voltage terminal to anode and negative voltage terminal to cathode, otherwise it gets destroyed. But can a polarized capacitor survive when AC voltage is applied, where the polarity of source generator is constantly changing, therefore half of the period capacitor is polarized the wrong way, so in that case capacitor would be destroyed? -> in case of capacitor applied directly to AC generator.
I know that for polarized cap, the "reverse voltage" can be as high as 2V for some period of time and the cap still survives it.
