Question
**Problem 7.** Find the equivalent inductance between points a and b. Assume that initial energy stored in the inductors is zero. ### Diagram (a) The circuit in diagram (a) includes the following inductors: - A series connection of a 12 H inductor between points a and the first node, and a 5 H inductor to the second node. - A parallel connection beneath this series, consisting of: - A 10 H inductor. - A loop consisting of an 80 H inductor and a 60 H inductor connected in parallel, leading down to a 15.8 H in series. - Beyond this configuration, a 6 H inductor is in series leading to node b. - A 14 H inductor connects in parallel across the rightmost node to node b. - A 24 H in parallel goes from node a directly to node b. ### Diagram (b) The circuit in diagram (b) includes the following inductors: - A series connection of a 21 H inductor between points a and the first node, with a 4 H inductor further in series. - From the same first node, a separate loop of: - A parallel connection containing a 44 H inductor leading to node b. - A series pathway of a 1.2 H inductor connecting to a horizontal 12 H in parallel with node b. - A 15 H inductor in parallel connecting to the second node. - From the second node, a 10 H inductor connects through to a 25 H in parallel, leading directly to node b. For calculations, you would combine the series and parallel inductors using the appropriate formulas to find the equivalent inductance between points a and b.
