Consider two parallel-plate capacitors, C1 and C2, that are connected in parallel. The capacitors are identical except that C2 has a dielectric inserted between its plates. A voltage source of 200 V is connected across the capacitors to charge them and is then disconnected.
(a) What is the charge on each capacitor?
(b) What is the total stored energy of the capacitors?
(c) The dielectric is removed from C2. What is the final stored energy of the capacitors?
(d) What is the final voltage across the two capacitors?
