If a smaller rated voltage capacitor is substituted in place of a higher rated voltage capacitor, the increased voltage may damage the smaller capacitor. Also we remember from the last tutorial that with a polarised electrolytic capacitor, the positive lead must go to the positive connection and the negative lead to the negative connection otherwise it may again become damaged. - Download [PDF]

Fuel cells, batteries, and super-capacitors have the highest energy densities, but due to their …
Given that the capacitors have a voltage rating of 100 volts, if they have the same value then the peak voltage withstand for two in series is 200 volts. If one capacitor is low in value by 10% and one is high by 10% there will be 20% more voltage seen across the lower value capacitor hence, you can''t really assume a 200 volt pulse withstand capability and it will be more like 160 volts.

Breakdown voltage is a characteristic of an insulator that defines the maximum voltage difference that can be applied across the material before the insulator conducts. In solid insulating materials, this usually [citation needed] creates a weakened path within the material by creating permanent molecular or physical changes by the sudden current.
Capacitance is defined as the total charge stored in a capacitor divided by the voltage of the power supply it''s connected to, and quantifies a capacitor''s ability to store energy in the form of electric charge. Combining …
My understanding of capacitors in series is that they have to have the same amount of charge on each plate. Using V = Q/C, this indicates that the smallest capacitors should have the highest voltage. But, whether I use a battery or DC regulated power supply, I keep seeing that the biggest capacitors use the most voltage.
