Question

Assume that the initial energy stored in the inductors below is zero. Find the equivalent inductance with
respect to the terminals a, b. 

### Inductor Circuit Diagram This diagram showcases a network of inductors, depicted by standard coil symbols, along with their respective inductance values in millihenries (mH). The circuit is between two points labeled 'a' and 'b'. Here's a detailed breakdown: 1. **In the Upper Pathway:** - There is a 20 mH inductor connected directly from point 'a'. - This is in series with a 7 mH inductor. 2. **In the Central Section:** - There is a diagonal 12 mH inductor bridging the upper and lower pathways. - Additionally, a 35 mH inductor is vertically aligned in the center. 3. **In the Lower Pathway:** - An 8 mH inductor is connected directly from point 'b'. - This is followed by a 24 mH inductor. 4. **Towards the Right Side:** - A 15 mH inductor is connected, completing the path between the upper and lower pathways. ### Key Observations: - The diagram displays a combination of serial and parallel inductor connections. - Understanding this configuration is crucial for analyzing the total inductance within this circuit. - Each inductor’s inductance is clearly labeled, assisting in calculations for total inductance, impedance, and current behavior in AC circuits. This kind of circuit analysis is foundational in electrical engineering, contributing to the understanding of filter designs, tuning circuits, and energy storage systems.
