8.2: Capacitance and Capacitors
If a circuit contains nothing but a voltage source in parallel with a group of capacitors, the voltage will be the same across all of the capacitors, just as it is in a resistive parallel circuit. If the circuit instead consists of …
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 .
How to choose capacitor voltage rating for ESD protection?
The capacitors will need to have a voltage rating that is higher than the highest DC voltage that will ever be across that capacitor during normal operation. The idea of proper ESD protection using capacitors is that the voltage will never become very high in the first place.

How can I choose an ESD protection capacitor? | FAQ
A. The first step is to confirm how much ESD protection is required. Keep in mind that a 12,000V module level requirement does not mean that the component requirement is also 12,000V. This relationship tells us how much voltage (Vx) our capacitor (Cx) will really ...
