An inductor of $\displaystyle 0.5$ mH , a capacitor of $\displaystyle 20 \mu \mathrm{~F}$ and resistance of $\displaystyle 20 \Omega$ are connected in series with a $\displaystyle 220$ V ac source. If the current is in phase with the emf, the amplitude of current of the circuit is $\displaystyle \sqrt{x} \mathrm{~A}$. The value of $\displaystyle x$ is -
