MCQ - Alternating Currents
question_answer
In a series LCR circuit, resistance, voltage and frequency of the main supply is \[200\text{ }\Omega ,\text{ }220\text{ }V\]and 50 Hz respectively. If capacitor is taken out from the circuit, the current lags behind the voltage by \[30{}^\circ \]. If inductor is taken out from the circuit, the current leads the voltage by \[30{}^\circ \]. The power dissipated in LCR-circuit is:
