Combination of Capacitors

The potential difference that must be applied across the parallel and series combination of three identical capacitors such that the energy stored in them becomes the same. The ratio of potential difference in parallel to series combination is

Show answer and solution

Answer: (a)

$C_p = 3C$ , $C_s = \frac{C}{3}$ .
Equal energy: $C_pV_p^2 = C_sV_s^2 \Rightarrow \frac{V_p}{V_s} = \sqrt{\frac{C_s}{C_p}} = \sqrt{\frac{1}{9}}$ .
$\frac{V_p}{V_s} = \frac{1}{3}$ .
So the answer is (a) $1 : 3$ .
