Three identical isolated capacitors, each with capacitance C, are connected in parallel, with a 11.7 V potential difference across their plates. Each capacitor carries a charge of 5.75 µC.
(a) Find C.
(b) Find the equivalent capacitance.
(c) Suppose that one of the capacitors is first disconnected and then reconnected with its terminals reversed. Find the final voltage drop across the capacitors.
