Question
Find the ratio of energy stored in the two configurations if they are both connected to the same source.

Solution
Energy for series combination
`E_s =1/2 C_(eq.s)V^2 = 1/2 xx 2xx 10^-6 xx V ... (1)`
Energy for parallel combination
`E_p =1/2 C_(eq.p)V^2 =1/2 xx 18 xx 10^-6 xx V ....(2)`
As both are connected to the same source
Hence, `E_s/E_p = (1/2 xx 2 xx 10^-6 xx V)/(1/2 xx 18 xx10^-6 xx V) = 1/9`
