Question
In the circuit of Fig. 7_1, what is \( L_{\text{eq}} \)? **Diagram Description:** - The circuit includes several inductors: - A 2H inductor in series with two 4H inductors in a parallel configuration. - Another 4H inductor follows in series from point a to point b. - From this point, a separate section has a 10H inductor connected in parallel with an 8H and a 2H inductor. **Options for \( L_{\text{eq}} \) Calculation:** - \( L_{\text{eq}} = 7 \, \text{H} \) - \( L_{\text{eq}} = 17 \, \text{H} \) - \( L_{\text{eq}} = 5 \, \text{H} \) - \( L_{\text{eq}} = 15 \, \text{H} \) - \( L_{\text{eq}} = 20 \, \text{H} \) - \( L_{\text{eq}} = 32 \, \text{H} \) **Understanding the Diagram:** - Inductors in series are added directly. - Inductors in parallel follow the reciprocal rule for calculating the equivalent inductance: \[ \frac{1}{L_{\text{eq}}} = \frac{1}{L_1} + \frac{1}{L_2} + \frac{1}{L_3} + \ldots \]
