Disc capacitors tend to crack open if overloaded-the polarity does not matter. Unless you overvoltage them or reverse voltage them or have a high current ripple in the DC power line beyond the capacitors rating they are …
The Fundamentals of Capacitors in AC Circuits
When an ac voltage is applied to a capacitor, it is continually being charged and discharged, and current flows in and out of the capacitor at a regular rate, dependent on the supply frequency. An AC ammeter connected in the circuit would indicate a current flowing through the capacitor, but the capacitor has an insulating dielectric between the two plates, so …
