A capacitor of capacitance $\displaystyle C$ and potential $\displaystyle V$ has energy $\displaystyle E$. It is connected to another capacitor of capacitance $\displaystyle 2$ C and potential $\displaystyle 2$ V. Then the loss of energy is $\displaystyle \frac{x}{3} \mathrm{E}$, where $\displaystyle x$ is $\displaystyle \_\_\_\_$.
