For which 2 reasons the discussion of LC oscillations is not realistic ?

Text Solution

Verified by Experts

(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 wave.
In face, radio and TV transmitters depend on this radiation.
