In the question number 30, the net power absorbed by the circuit in one complete cycle is

Answer»

5 W
10 W
15 W
zero

Solution :As `P = V_("rms")I_("rms")cos phi`
In a PURE capacitance circuit, the phase difference between alternating VOLTAGE and CURRENT is `pi//2` . Hence
`P = V_("rms")I_("rms")cos 90^(@) = 0`.
