A circuit containing a 80 mH inductor and a 60 μF capacitor in series is connected to a 200 V, 50 Hz supply. The resistance of the circuit is negligible. The average power (average over one cycle) transferred to capacitor is: |
1.2 W 6 kW 1.2 MW 0 |
0 |
The correct answer is Option (4) → 0 The average power over one cycle is zero, because the energy stored in the electric field of the capacitor, is equal to the energy released in the next cycle. |
