question_answer
In a series LCR circuit\[R=200\,\,\Omega \]and the voltage and the frequency of the main supply is 220 V and 50 Hz respectively. On taking out the capacitance from the circuit the current lags behind the voltage by\[30{}^\circ \]. On taking out the inductor from the circuit the current leads the voltage by 30°. The power dissipated in the LCR circuit is - [AIEEE 2010]
