Solved An AC source operating at 60 Hz with a maximum
An AC source operating at 60 Hz with a maximum voltage of 171 V is connected in series with a resistor (R = 1.0 k 2) and a capacitor (C = 2.5 uF). (a) What is the maximum value of the current in the circuit?
While an ordinary electrostatic capacitor may have a high maximum operating voltage, the typical maximum charge voltage of a supercapacitor lies between 2.5 and 2.7 volts. Supercapacitors are polar devices, meaning they have to be connected to the circuit the right way, just like electrolyte capacitors.

Explaining Capacitors and the Different Types | DigiKey
A capacitor''s voltage rating is an indication of the maximum voltage that should be applied to the device. The context of the rating is significant; in some instances it may indicate a maximum safe working voltage, in others it may be more akin to a semiconductor''s "absolute maximum" rating, to which an appropriate de-rating factor ...

IEEE Standards Interpretations for IEEE Std 18™-2002 IEEE …
Guidelines for protection of shunt capacitor banks can be found in IEEE C37.99. Capacitor banks are not intended to be applied where the maximum operating voltage exceeds the nominal voltage rating of the capacitor bank. If a power system operates at higher than nominal system voltage then the user should take that into consideration
This is the maximum voltage at which the capacitor operates without leaking excessively or arcing through. This working voltage is expressed in terms of DC but the AC equivalent is about only one half of that DC rating. As the AC frequency increases the working voltage rating decreases further still.
