It can be found in the datasheet of the capacitor supplied by its manufacturer.
The Working Voltage is another important capacitor characteristic that defines the maximum continuous voltage either DC or AC that can be applied to the capacitor without failure during its working life. Generally, the working voltage printed onto the side of a capacitors body refers to its DC working voltage, (WVDC).
That is, the value of the voltage is not important, but rather how quickly the voltage is changing. Given a fixed voltage, the capacitor current is zero and thus the capacitor behaves like an open. If the voltage is changing rapidly, the current will be high and the capacitor behaves more like a short.
If the capacitor is ideal the current would rapidly attain the limiting value corresponding to the IR. The ideal current curve is designated I C-ideal. But because the polarization in the dielectric requires a finite time for dipoles to reorient the real charging current follows the curve I C-polarization. Figure 2.
Equation 6.1.2.6 6.1.2.6 provides considerable insight into the behavior of capacitors. As just noted, if a capacitor is driven by a fixed current source, the voltage across it rises at the constant rate of i/C i / C. There is a limit to how quickly the voltage across the capacitor can change.
Therefore we can state a particularly important characteristic of capacitors: The voltage across a capacitor cannot change instantaneously. (6.1.2.7) (6.1.2.7) The voltage across a capacitor cannot change instantaneously. This observation will be key to understanding the operation of capacitors in DC circuits.
