What are LC oscillations?

LC circuit:a resonant circuit, tank circuit, or tuned circuit, is an electric circuit consisting of an inductor,L, and a capacitor,  C, connected together. The circuit can act as an electricalresonator, an electrical analogue of a tuning fork, storing energy oscillating at the circuit's resonant frequency. These oscillations are called LC oscillations.

For example, we investigated the effect of driving a mechanical oscillator with an external force, which leads to the phenomenon of resonance. We observe the same phenomenon in the LC circuit.

For example, a radio tuner has an LC circuit with a natural frequency, which we determine as follows: When the circuit is driven by the electromagnetic oscillations of a radio signal detected by the antenna, the tuner circuit responds with a large amplitude of electrical oscillation only for the station frequency that matches the natural frequency.
