For which two reasons is the discussion of $LC$ oscillations not realistic?
(N/A) $(i)$ Every inductor has some resistance. The effect of this resistance is to introduce a damping effect on the charge and current in the circuit,and the oscillations finally die away.
$(ii)$ Even if the resistance were zero,the total energy of the system would not remain constant. It is radiated away from the system in the form of electromagnetic waves.
In fact,radio and $TV$ transmitters depend on this radiation.
