1. The problem statement, all variables and given/known data Six identical capacitors with capacitance C are connected as shown in figure 30.68 (attachment). What is the potential difference between points a and b? 2. Relevant equations C=Q/V 3. The attempt at a solution The Cequivalent = 3/2 C Therefore, Q = CV = (3/2C)(12) = 18 C since capacitors in parallel have the same potential difference, the two capacitors that are in parallel between point a and b have the potential difference, V = Q/C = 18C/(C) = 18 Thus, the two capacitors between point a and b, have a combined potential difference of 36V. Is this correct?
