A) Current \[\text{I(t),}\] lags voltage V(t) by \[\text{9}{{\text{0}}^{o}}.\]
B) Over a full cycle the capacitor C does not consume any energy from the voltage source.
C) Current\[\text{I(t)}\] is in phase with voltage V(t).
D) Current \[\text{I(t)}\]leads voltage V(t) by \[\text{18}{{\text{0}}^{o}}.\]
Correct Answer: B
Solution :
\[Power={{V}_{rms,}}.{{I}_{rms}}\cos \,o|\] as \[\cos \,o|=0\] (Because \[o|={{90}^{o}}\]) \[\therefore \]Power consumed = 0 (in one complete cycle)
