One more thing I forgot to add regarding one of your earlier posts:
To get A3 to read zero, you have to first connect the source to "put some energy into the LC network", then disconnect the source at a particular instant so that the energy will start oscillating between L and C, and then reconnect the source at a particular instant such that no current is drawn from the source.
Altering the frequency continuously till you hit resonance won't make A3 read zero, because whatever transient starts after you connect the source, lasts forever as there is no resistive damping. This is why I used the term "undamped transient" earlier somewhere. (Though if it lasts forever, it's no longer "transient", but I don't know what I should call it:-p).

All the ac circuits you have in your curriculum are assumed to be in sinusoidal steady state and concepts like phasors (and phasor algebra), impedance, real/reactive power etc are applicable only to the circuits in sinusoidal steady state.

I was waiting for this post . This is why I hadn't marked it as solved :smile:

Thank you very much !
