Three capacitors are arranged as shown as a portion of a complete circuit. ?2 and ?3 are wired in parallel, and then the system of (?2 + ?3) is wired in series to capacitor ?1. The capacitances of each capacitor are ?1 = 5.1 ??, ?2 = 4.8 ??, and C3= 6.2 ??. There is an unknown potential difference between points a and b. a. What is the equivalent capacitance of the system? b. If the charge on ?2 is 22 ??, what are the charges on ?1 and ?3? c. What is the voltage between points a and b?
