(N/A) An $LC$ circuit is an electrical circuit consisting of an inductor with negligible resistance connected in parallel with a capacitor.
$LC$ oscillations refer to the process where a charged capacitor discharges through an inductor,causing energy to oscillate between the electric field of the capacitor and the magnetic field of the inductor. This results in electrical oscillations of constant amplitude and constant frequency,assuming no energy loss.
