At steady state current will not be in the capacitor branch.
\begin{aligned} & i=\frac{4}{6+2+8} \\ & \mathrm{i}=\frac{1}{4} \mathrm{~A} \\ & \Delta \mathrm{V}_{\mathrm{C}_1}=\mathrm{i}(6+2) \\ & \Delta \mathrm{V}_{\mathrm{C}_2}=\mathrm{i}(2+8) \\ & \frac{\Delta V_{\mathrm{C}_1}}{\Delta \mathrm{V}_{\mathrm{C}_2}}=\frac{4}{5} \\ & \end{aligned}
