A battery is connected purely in parallel to three capacitors of C1 = 6 micro-farads, C2 = 9 micro-farads, and C3 = 11 micro-farads. Then, one additional capacitor of 8 micro-farads is added in parallel to the other three capacitors and due to this, the total stored energy of all the capacitors increases by 196 micro-joules (it is 196 micro-joules larger with four capacitors compared to with three capacitors). Then, the same four capacitors are connected in SERIES to the...
