Q1

An LCR circuit contains resistance of \(110\Omega\) and a supply of \(220\mathrm{V}\) at \(300\mathrm{rad}/s\) 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:
