- Zero.
- We have $\text{C}_{series} = \frac{3\mu\text{F}}{3} =1 \mu\text{F}$
Energy stored $ = \frac{1}{2}\text{CV}^{2}$
$\therefore$Energy in series combination $ =\frac{1}{2}1 \times10^{-6}\times\text{V}^{2}$
Energy in parallel combination $ =\frac{1}{2}9 \times10^{-6}\times\text{V}^{2}$
$\therefore$ Ratio = 1:9.
