Capacitor Characteristics

When the leakage is very low such as in film or foil type capacitors it is generally referred to as "insulation resistance" ( R p ) and can be expressed as a high value resistance in parallel with the capacitor as shown. When the leakage current is high as in electrolytic''s it is referred to as a "leakage current" as electrons flow directly through the electrolyte.

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
