What happens if I connect a low voltage rated capacitor to a high voltage?
When that happens, you don''t have a capacitor any more. In the best case you are left with a short circuit or an open circuit. In the worst case you have a lab full of smoke and/or a trip to the ER. Capacitor manufacturers are quite helpful in printing the maximum voltage their caps will stand before they stop being capacitors.

Explaining Capacitors and the Different Types | DigiKey
Whereas the rule of thumb for designing with Ta/MnO 2 capacitors is to de-rate voltage by 50% (or more if series resistance is very low), the leading manufacturer of NbO-based devices (AVX) has suggested that de-rating voltage by only 20% is sufficient for safe operation. Additional de-rating beyond these levels can improve long-term ...

What is the lowest capacitor voltage rating that is safe to use?
The lighter the stress on a capacitor the less margin I will allow. For example, if a signal only very occasionally goes to 90V but is mostly below 50V then I might use a 100V ceramic capacitor. Temperature, voltage, current, and ESL/ESR effects all play into this. A capacitor with lots of stress will get much more of a margin.
When should I use a low ESR capacitor
When the AC source is low frequency (50 Hz, 60 Hz, 120 Hz...) the capacitors are physically large, and could tolerate high ESR (like, 1 ohm for a 1A supply with a 1000 uF filter capacitor). That''s because a one-amp ripple current only created one watt of heat, and a large (over a square inch of surface area) 1000uF capacitor can shed that heat.

How to Discharge a Capacitor
It is important to note that the best rating for low-voltage capacitors is a 5-watt 2kΩ resistor, while the best for high-voltage capacitors is a 5-watt 20kΩ resistor. The idea here is that the higher the resistance, the slower the transfer of energy from the capacitor, and the safer the discharge process is.
