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