High-voltage capacitor in a low-voltage system
The voltage rating of a capacitor is a measure of how strong its insulation is. A 35V cap can withstand at least 35 volts applied across it (a higher voltage may cause bad things like a short through the cap and burnup). It has nothing to do with how much voltage the capacitor will store; it can store nothing higher than is input to it.
