What happens if I connect a low voltage rated capacitor to a high voltage?

For a capacitor, one of the limits is keeping the voltage low enough that the capacitor dielectric stays intact. As you increase the terminal voltage, the electric stress increases across the dielectric, and eventually, it breaks down. When that happens, you don''t have a capacitor any more. In the best case you are left with a short circuit or ...
