NEET Solved Paper 2016 Question 43
Question: A small signal voltage $ \text{V(t) = }{V_0},\sin \omega t $ is applied across an ideal capacitor C :-
Options:
A) Current $ \text{I(t),} $ lags voltage V(t) by $ 9{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 $ 18{0^{o}}. $
Show Answer
Answer:
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)
