### RLC Circuit Analysis

**Diagram Description:**

In the given schematic, we have an RLC circuit containing the following components:

- **Voltage Source:** The circuit has an AC voltage source given by \(36 \cos(3t - 60^\circ)\) volts. This represents a time-varying voltage with an amplitude of 36 volts and a phase shift of -60 degrees.

- **Resistor:** A resistor with a resistance of \(9 \, \Omega\) is connected in series with the circuit.

- **Inductors:** There are three inductors in the circuit:
  - The first inductor has an inductance of \(2 \, \text{H}\).
  - The second inductor is parallel to another series combination and has an inductance of \(2 \, \text{H}\).
  - The third inductor with an inductance of \(4 \, \text{H}\) is in the series combination.

- **Capacitor:** There is a capacitor with a capacitance of \(1/18 \, \text{F}\) in parallel with the second inductor.

- **Voltage across the Inductor-Capacitor Branch:** The circuit indicates a potential difference across the parallel branch containing the \(2 \, \text{H}\) inductor and the \(1/18 \, \text{F}\) capacitor, denoted by \(v\).

This RLC circuit is a common configuration used to study resonance, impedance, and phase relationships in AC circuits. Analyzing such a circuit involves calculating the total impedance and the phase angle between the input voltage and the resulting current.
