An LCR circuit contains resistance of $\displaystyle 110 \Omega$ and a supply of $\displaystyle 220$ V at $\displaystyle 300 \mathrm{rad} / \mathrm{s}$ angular frequency. If only capacitance is removed from the circuit, current lags behind the voltage by $\displaystyle 45^{\circ}$. If on the other hand, only inductor is removed the current leads by $\displaystyle 45^{\circ}$ with the applied voltage. The rms current flowing in the circuit will be :
