Capacitors and capacitance
Since C 1 and C 2 are connected in series then
Q 2 =Q 3 =Q′=38.2µC
To find the potential difference on each capacitor we use the relation
V=Q/C
Then,
V 1 =25.45V
V 2 =6.37V
V 3 =19.1V
Example 6.9
Consider the circuit shown in figure 6.12 where C 1 =6µF, C 2 =4µF,
C 3 =12µF, and V=12V.
