Why are capacitors polarized?

Electrolytic capacitors are polarised components for their asymmetric construction and must be activated with a voltage (i.e. more positive) on the anode above the cathode at any time.

RELATED QUESTIONS

Why we use polarized capacitor?
Electrolytic capacitors are the most popular polarized capacitors. They offer high capacity values in a small economic package. Their main use is to filter the electrical energy (storage). They are also used in coupling the amplifier passage to block DC.
Why do polarized capacitors explode?
If a high voltage is applied above the nominal value to the capacitor, its dielectric force will degrade and eventually the capacitor will explode. Electrolytic capacitors fail due to the loss or vaporization of the internal electrolyte. Inadequate polar connections of these capacitors can cause explosion or failure.
Why are electrolytic capacitors polarized?
Electrolytic capacitors are polarized components due to their asymmetrical construction and must operate with a higher voltage (i.e. more positive) in the anode than in the cathode at any time. Therefore, the terminal of the anode is marked with an extra sign and the cathode with a less sign.
Why do capacitors pass AC?
If a constant voltage (DC) is applied to a capacitor that is not charged, it is charged up to a value determined by voltage and capacity (QCV). That's why it is said that capacitors block DC. If the voltage always changes over time (AC), the capacitor tries to keep it constant.
How do polarized capacitors work?
Capacitors are asymmetrical and must be operated with a higher voltages on the anode than on the cathode at all times. The terminal is marked with a plus sign and a minus sign for this reason.
