This image illustrates an LC (inductor-capacitor) circuit. It consists of the following components:

1. **Capacitor (C):** On the left side of the circuit, represented by parallel lines, the capacitor holds an electric charge \( Q_{\text{max}} \). The positive and negative terminals are indicated, showing that it is charged.

2. **Inductor (L):** On the right side, represented by a coil symbol, the inductor stores energy in a magnetic field when current flows through it.

3. **Switch (S):** Located at the bottom, this switch can open or close the circuit.

The circuit diagram shows the DC current path when the switch (S) is closed. Initially, when the switch is closed, the capacitor will start discharging through the inductor, which can lead to oscillations of energy between the electric field of the capacitor and the magnetic field of the inductor, characterizing an LC oscillating circuit.
