(adsbygoogle = window.adsbygoogle || []).push({}); 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?
