Two parallel-plate capacitors C1 and
C2 are connected in series to a battery. Both
capacitors have the same plate area of 3.40 cm2 and
plate separation of 2.65 mm. However, the first capacitor

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...

A parallel combination of two capacitors, C1 and

Two capacitors, C1=5900pF and C2=2600pF, are connected in series
to a 15.0 V battery. The capacitors are later disconnected from the
battery and connected directly to each other, positive plate to
positive plate, and negative plate to negative plate. What then
will be the charge on each capacitor?

Two capacitors are connected parallel to each other and
connected to the battery with voltage 25 V . Let C1 = 9.5 μF ,C2 =
5.0 μF be their capacitances. Suppose the charged capacitors are
disconnected from the source and from each other, and then
reconnected to each other with plates of opposite sign together.By
how much does the energy of the system decrease?

Two capacitors C1 = 5.6 μF, C2 = 15.1 μF
are charged individually to V1 = 18.0 V, V2 =
5.7 V. The two capacitors are then connected together in parallel
with the positive plates together and the negative plates
