In a series LCR circuit R=200(Ω) and the voltage and the frequency of the main supply is 220V and 50 Hz respectively. On taking out the capacitance from the circuit the current lags behind the voltage by 30(∘). On taking out the inductor from the circuit the current leads the voltage by 30(∘). The power dissipated in the LCR circuit is
