### Circuit Diagram: Inductive Network

**Components:**
1. **Current Source (\(i_s\))** - This is an ideal current source represented by a circle with an arrow inside pointing upwards. It supplies a constant current \(i_s\) to the circuit.
  
2. **Inductors** - There are three inductors in the circuit:
    - **20 mH Inductor** (\(i_1\)) - Placed parallel to the current source. It is labeled with the current \(i_1\).
    - **4 mH Inductor** (\(i_2\)) - Placed in series with a 6 mH inductor. This inductor is labeled with the current \(i_2\).
    - **6 mH Inductor** - Connected in series with the 4 mH inductor.
  
3. **Voltage Measurement (\(v_o\))** - The voltage across the 20 mH inductor is denoted as \(v_o\), with the positive terminal on the top side and the negative terminal on the bottom side.

4. **Net Inductance (\(L_{eq}\))** - This label is placed below the circuit diagram and is used to represent the equivalent inductance of the given inductive network.

### Circuit Description
This diagram is an illustrative example of an inductive network in which inductors are combined in both parallel and series configurations. The circuit utilizes an ideal current source to drive the network. 

- The **20 mH inductor** on the left side of the circuit is parallel to the branch containing the **4 mH and 6 mH inductors** which are connected in series.
- The labeled currents \(i_1\) and \(i_2\) represent the current through the 20 mH inductor and the series combination of the 4 mH and 6 mH inductors, respectively.
- The net inductance of this circuit can be calculated by considering the parallel and series combinations of the inductors involved.

### Analysis
- To analyze this circuit, you can use Kirchhoff's laws and the rules for combining inductances in series and parallel. 
- The voltage \(v_o\) across the 20 m
