Learn MoreThe usable energy in the single string of eight (in series) is W = 1*[(10F/8)/2*((2.7V*8)2-6V2)] = 269.1J Since both capacitor banks store the same total energy, the string with lower voltage has a greater percentage of charge wasted/unusable. In this case, the higher string voltage is preferable to fully utilize the SCs.
