In the question number 30, the net power absorbed by the circuit in one complete cycle isA. 5 WB. 10 WC. 15 WD. zero |
Answer» Correct Answer - D 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`. |
