An LC oscillator shows how energy repeatedly transfers between a capacitor and an inductor to generate a continuous sine wave without any external AC input. When the switch is flipped, a sudden burst of energy is applied to the circuit, which appears as the sharp start of the waveform. The capacitor first stores energy in the electric field, then releases it into the inductor, where it becomes magnetic energy. As the magnetic field collapses, current continues to flow and recharges the capacitor

This simulation demonstrates an LC Oscillator, where energy continuously transfers between the inductor and capacitor, producing oscillations. The waveform shows the voltage across the inductor (green), the current through the inductor (yellow), and the current through the capacitor (red). As the capacitor charges and discharges, it drives current through the inductor, creating sinusoidal oscillations at the circuit’s resonant frequency (around 159 kHz here). This highlights the fundamental prin
