How do you find the voltage across a capacitor at time t= 0 and t ...
Once you know t the voltage on C can be more easily calculated. The voltage on C will change by 63% of the applied voltage (applied across RC) after each t time period. This works for charging or discharging. (In discharging you could say the voltage is at 37%, however this is the same as saying a 63% decrease.)
Ceramic Capacitor FAQ and Application Guide
Even when used within the capacitor''s maximum operating temperature, these capacitors may require a reduced voltage to maintain reliability. However, KEMET ceramic capacitors are designed and qualified to operate at full-rated temperature and voltage.
18.4: Capacitors and Dielectrics
The maximum energy (U) a capacitor can store can be calculated as a function of U d, the dielectric strength per distance, as well as capacitor''s voltage (V) at its breakdown limit (the maximum voltage before the dielectric ionizes and no longer operates as an insulator):
18.5 Capacitors and Dielectrics
If a capacitor is charged by putting a voltage V across it for example, by connecting it to a battery with voltage V—the electrical potential energy stored in the capacitor is U E = 1 2 C V 2 . U E = 1 2 C V 2 .

OverviewNon-ideal behaviorHistoryTheory of operationCapacitor typesCapacitor markingsApplicationsHazards and safety
In practice, capacitors deviate from the ideal capacitor equation in several aspects. Some of these, such as leakage current and parasitic effects are linear, or can be analyzed as nearly linear, and can be accounted for by adding virtual components to form an equivalent circuit. The usual methods of network analysis can then be applied. In other cases, such as with breakdown voltage, the effec…

CAPACITOR WORKING VOLTAGE AND DIELECTRIC …
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.
Capacitor Specifications: what they mean
The capacitor''s voltage rating should always be at least 1.5 times or twice the maximum voltage it may encounter in the circuit. Capacitors are not as reliable as resistors. They get easily damaged once the applied voltage nears …

Understanding voltage rating of a capacitor
The DC working voltage is the maximum DC voltage and NOT the maximum AC voltage. A capacitor with a DC voltage rating of 100 volts DC cannot be safely used to an AC voltage of 100 volts. This is because an alternating voltage that has an RMS value of 100 volts will have a peak value over 141 volts (√2 x 100).

To find the maximum current, the maximum energy in the capacitor is set equal to the maximum energy in the inductor.
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 …
Electrolytic Capacitor
An electrolytic capacitor is a passive component used to store electrical energy temporarily, and it is made of an anode, an oxide used as dielectric film and an electrolyte (solid or nonsolid) as counter electrode containing a metallic cathode. From: Encyclopedia of Interfacial Chemistry, 2018
