### RLC Circuit Diagram

This image depicts a simple RLC circuit which consists of:

1. **AC Voltage Source:** Represented by a circle with a sine wave inside it. It provides alternating current to the circuit.

2. **Resistor (R):** Indicated by a zig-zag line. It opposes the flow of current, dissipating energy as heat.

3. **Inductor (L):** Shown as a coiled line to the right of the resistor. It stores energy in a magnetic field when electricity passes through it.

4. **Capacitor (C):** Depicted as two parallel lines. It stores energy in an electric field between its plates and can block direct current while allowing alternating current to pass.

These components are connected in series, forming a complete electrical loop used to study the behavior of AC circuits in terms of impedance and phase relationships.
