A) Current I (t), lags voltage V (t) by \[90{}^\circ \].
B) Over a fall cycle the capacitor C does not consume any energy from the voltage source.
C) Current I (t) is in phase with voltage V (t).
D) Current I (t) leads voltage V (t) by \[180{}^\circ \].
Correct Answer: B
Solution :
[b] As we know, power \[P={{V}_{rms}}.{{I}_{rms}}\,\cos \,\phi \] as \[\cos \,\phi =0\] \[(\because \,\,\,\,\phi ={{90}^{o}})\] \[\therefore \] Power consumed =0 (in one complete cycle)
