This slow decay within amplitude which tends to the loss of an oscillation is known as damping. These imperfections will waste some amount of energy among the cycles which result in the amplitude loss gradually and finally, the oscillations will disappear. However, in a practical case, the inductor will have some ohmic resistance and the capacitor will have some amount of leakage. If an ideal capacitor & inductor are used, this oscillation will maintain until the end of time. In the oscillator circuit, the transfer of cyclic energy among the capacitor & inductor is the reason behind the production of oscillations in the tank circuit. After that again the capacitor will start discharging. Once the capacitor is charged completely, then the stored energy within the inductor like an electromagnetic field will be shifted to the capacitor like an electrostatic field. So again this back emf will start charging the capacitor. So, the conductor will generate back emf because of electromagnetic induction to resist the change within the current. So, there is no more energy within the capacitor to maintain the flow of current in the coil, the field in the region of the coil will start to reduce & the flow of current throughout the coil will reduce. These types of oscillators use tank circuits including the components like a capacitor (C) and an inductor (L).

LC oscillators are used in heating with high-frequency, RF generators, radios, TV receivers, etc. By using the practical values of capacitors and inductors, it is possible to generate high range frequencies like > 500 MHz. This circuit is also called an LC-tuned LC resonant or tank circuit. LC oscillator definition is an oscillator that is used to generate high-frequency signals which are also known as RF oscillator. The LC oscillator circuit ignores the dissipation energy caused through resistance. It is applicable for tuners, oscillation circuits, mixers & filter circuits, etc. The LC oscillator circuit is mainly used to produce signals with a specific frequency. The main essence of resonance is that the energy of the magnetic field within the inductance & the energy of the electric field within the capacitor can be changed into each other.
In this condition, the circuit reaches the whole impedance or high value. Once the LC circuit reaches this condition, then it is known as resonance. If you change the circuit components or the power frequency, then the whole circuit will appear simply resistive.
In an AC circuit including an inductor & a capacitor, the current and the phase of the voltage are usually different.
