Unformatted text preview: of 3.00 F and 6.00 F capacitors are in parallel with each other and the two pairs are in series. Solution EXECUTE: Qtotal CeqV 1 (a) With the switch open Ceq 3F 1 1 6F 1 3F 1 1 6F 4.00 F . (4.00 F) (210 V) 8.40 10 4 C . By symmetry, each capacitor carries 4.20 10 voltages are then calculated via V Q / C . This gives Vad Q / C3 140 V and Vac Q / C6 4 C. The 70 V . Vcd Vad Vac 70 V . (b) When the switch is closed, the points c and d must be at the same potential, so the equivalent capacitance is Ceq 1 (3.00 6.00) F 1 (3.00 6.00) F 1 4.5 F ....
