Write a short paragraph (5+ sentences) describing the sequence (full cycle) of
how oscillations in an LC circuit proceed at the resonant frequency. In particular, mention the
transfer of electric and magnetic field energy, the direction of the current, and the charges on the
capacitor plates at several different points in the cycle. You may draw pictures to support of your
description.

Answer #1

Suppose the capacitor initially has charge Q0 . When the switch is closed, the capacitor begins to discharge and the electric energy is decreased.

On the other hand, the current created from the discharging process generates magnetic energy which then gets stored in the inductor. In the absence of resistance, the total energy is transformed back and forth between the electric energy in the capacitor and the magnetic energy in the inductor.This phenomenon is called electromagnetic oscillation or lc oscillation.

Below is schematic representation of energy transfer in one cycle of LC oscillation. Please find the image attached below

T = time period of oscillation
