In a series circuit and the voltage and the frequency of the main supply is and respectively. On taking out the capacitance from the circuit the current lags behind the voltage by . On taking out the inductor from the circuit the current leads the voltage by . The power dissipated in the circuit is:
- A
- B
- CZero W
- D
