Solution 43 V Q4 180 C, V4 65 V 87 V Q3 180 C, V3 Solu<on V3 V4 V2 and V1 V2 V5 220 V (apart from some small rounding error) Q1 Q2 Q3 and Q5 Q2 Q4 IDENTIFY: Apply the rules for combining capacitors in series and in parallel. SET UP: With the switch open each pair of 3.00 F and 6.00 F capacitors are in series with each other and each pair is in parallel with the other pair. When the switch is closed each pair of 3.00 F and 6.00 F capacitors are in parallel with each other and the two pairs are in series. EXECUTE: Qtotal CeqV 1 (a) With the switch open Ceq 3F 1 6F 1 1 3F 1 1 6F 4.00 F . (4.00 F) (210 V) 8.40 10 4 C .
