A) 5 W
B) 10 W
C) 15 W
D) zero
Correct Answer: D
Solution :
(d) zero As \[P={{V}_{rms}}{{l}_{rms}}\cos \phi \] In a pure capacitance circuit, the phase difference between alternating voltage and current is \[\pi /2\]. Hence \[P={{V}_{rms}}{{l}_{rms}}\cos \,90{}^\circ =0\]You need to login to perform this action.
