Question
Calculate the following series parallel network in polar notation
The circuit diagram illustrates an AC circuit with a current source with a magnitude of 5 A at a phase angle of 0°. The components of the circuit are as follows:

- **R1**: 2 Ω resistor
- **X_C**: 4 Ω capacitive reactance
- **X_L1**: 6 Ω inductive reactance
- The combination of **X_C** and **X_L1** is in parallel.
- **Z_T** represents the total impedance leading from the current source.
- **R2 and R3**: Two resistors, each with 8 Ω resistance, are in parallel.
- **X_L2**: 3 Ω inductive reactance in series with the parallel combination of R2 and R3.

The current from the source is denoted as **I = 5 A ∠ 0°**. The current **I_L** flows through the branch containing **X_L2**.

Below the diagram, blank boxes are provided for the calculation of:

- **Z_T**: Total impedance
- **I_L**: Current through the inductor **X_L2**
- **V2**: Voltage across R2 and R3 parallel combination
- **pf**: Power factor (leading or lagging)

These calculations help in understanding the behavior of the circuit in terms of impedance, current, voltage, and power factor.
