I need a confirmation about the rule that I learned in College too long ago.
When 2 capacitors of 25 uf - 100v are in a parrallel circuit the total capacitance for this circuit will be 12.5 uf at a mximum voltage of 100volts ?
When 2 capacitors of 25 uf - 100v are in a series circuit the total capacitance for this circuit will be 25 uf but maximum voltage of 200volts ?
Theses rules apply to Non-Polarized capacitors also ?
Please refresh my memory, thanks.

Capacitors in parallel sum. 2x25 = 50 uF, 100v in your case
capacitors in series Csum=1/(1/C1 + 1/C2) voltage the sum of the voltages of the caps (12.5 uF, 200V in your case).

I'll give the 200 Volt rating a big maybe. Capacitors in series may not divide the voltages evenly. Often a high value resistor is connected across each cap. to help with the voltage division.
When you say high value resistor what kind of value (in ohms) are we talking about ?
Also how many watt resistor do you recommend, 1/4 w, 1/8 w, 1/2 w, 1 watt, 2 watts ?
Ripple current and ESR
Hope this is not off topic.
What happens to ripple current and ESR when you parallel / series?
