When talking about capacitors its millions of joules of electrons moving across the plates opposing a change in voltage from one plate to another..... Capacitors are constant voltage items, and inductors are constant current items, they resist a current change in the line with their stored electromagnetic field. Both of these items work in a power supply to try and maintain a nice ripple free DC source. Working voltage, peak voltage, average voltage, Which was actually posted on the side of an electrolytic....? Unless you made it, you don't know... So when replacing go 10-20% above the highest V. you see in the working set..... Another reason it's good to fix the set before ordering new caps.... Is B+ above design specs...? Below...? Which is normal....? Was the set made with parts from the lowest bidder....? Does the cap even come close to the ratings posted on the side....? I usually buy electrolytics rated 50V above what I'm taking out, 75 to 100 if I can't get the 50. Last choice is to put back exactly what came out, never go under the rated voltage.
